Read a .properties file from a .jar file

2011-02-16T19:04:00.001-08:00

well this is an embrassing thing to share but this is the fact, that I found difficulties when i tried to read *.properties file when it's already in *.jar file first, I tried to load the properties file with this way :

   1: URL url = InOut.class.getClassLoader().getResource("appSetting/test.properties");   2: File f = new File(url.toURI());   3: FileInputStream fis =  new FileInputStream(f);   4: Properties prop  = new Properties();   5: prop.load(fis);   6: System.out.println(prop.getProperty("test"));

there's no problem when I try to run it from Eclipse, but when I already have exported it into a .jar file and try to run it, this error hit my screen... –____–

java.lang.IllegalArgumentException: URI is not hierarchical
at java.io.File.<init>(File.java:380)
at inOutTask.InOut.main(InOut.java:49)

well, I tried to load a Properties file from File object initiated with URI. And the URI comes from URL object that I have created in the first line : jar:file:/home/123/abc/test.jar!/appSetting/test.properties. as you can see it tried to load a properties file in a jar file. in my opinion we can't access file in a file.. so that's the problem. Actually method load() in line 5 accept an InputStream object, so why it could accept FileInputStreamObject? It's because FileInputStream is an extended class from InputStream. so to get around this problem I just need to pass an InputStream object to method load() with this way :

   1: InputStream is = ClassName.class.getClassLoader().getResourceAsStream("appSetting/test.properties");   2: Properties prop  = new Properties();   3: prop.load(is);   4: System.out.println(prop.getProperty("test"));

   1: InputStream is = ClassName.class.getResourceAsStream("/appSetting/test.properties");   2: Properties prop  = new Properties();   3: prop.load(is);   4: System.out.println(prop.getProperty("test"));

I use ClassName.class because I called this line of code from a main method, so if want to call this getResourceAsStream() method from a POJO class just change it into this.getClass(). the difference between those two are :

the first way ClassLoader.getResourceAsStream(path) will consider all paths to be absolute paths. So calling String.getClassLoader.getResourceAsString("myfile.txt") and String.getClassLoader.getResourceAsString("/myfile.txt") will both look for a file in your classpath at the following location: "./myfile.txt"
the second way in Class.getResourceAsStream(path), the path is interpreted as a path local to the package of the class you are calling it from. For example calling, String.getResourceAsStream("myfile.txt") will look for a file in your classpath at the following location: "java/lang/myfile.txt". If your path starts with a '/', the it will be considered an absolute path, and will start searching from the root of the classpath. So calling String.getResourceAsStream("/myfile.txt") will look at the following location in your in your class path "./myfile.txt

Setup POSTGRESQL with IDENT Authentication method

2010-12-26T07:15:00.001-08:00

Yoo... this thing takes several hours for me to make it works –____-,
I just can’t find a good example about this.
IDENT Authentication indeed really an evil one. (he said that) >:).

So here we go :

assuming that you already have installed your own POSTGRESQL on your workstation, if no, then this is a short step you need to take :

#yum install postgresql

#yum install pgadmin3 (optional)

by default, you can install POSTGRESQL when you installed fresh Fedora 14 (ehhmm... advertise :D). For the complete step you can read this.
For the first time using POSTGRESQL after installation you would need to do initialization

#service <postgresql_service_name> initdb

Ok, by default if you installed new version of POSTGRESQL e.g "PostgreSQL 8.4.5 on i386-redhat-linux-gnu" it will set the local and host authentication type into IDENT. Try to open the pg_hba.conf file : (you need root acces to edit this file)

# nano /etc/var/lib/pgsql/data/pg_hba.conf

then you'll find this part in it :

# TYPE DATABASE USER CIDR-ADDRESS METHOD 
# "local" is for Unix domain socket connections only 
local all all ident
# IPv4 local connections: 
host all all 127.0.0.1/32 ident
# IPv6 local connections: 
host all all ::1/128 ident

The ident authentication method works by inspecting the client's operating system user name and determining the allowed database user names by using a map file that lists the permitted corresponding user name pairs. You could read more about IDENT from here.

When we used IDENT authentication, we'll need IDENT server, it's used to answer questions like "What user initiated the connection that goes out of your port X and connects to my port Y?", now I'm using OIDENTD, to install OIDENTD you just need :
#yum install oidentd

you can read more about oidentd from here

Ok, let's begin to editing all files that necessary to makes IDENT Authentication works, start from postgresql's ident file :

# nano /var/lib/pgqsql/data/pg_ident.conf

add this configuration at the lowest line :

# MAPNAME     SYSTEM-USERNAME    PG-USERNAME 
test      uzer              postgres

now open again pg_hba.conf then add mapname into it :

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD 
# "local" is for Unix domain socket connections only 
local   all         all                               ident map=test
# IPv4 local connections: 
host    all         all         127.0.0.1/32          ident map=test
# IPv6 local connections: 
host    all         all         ::1/128               ident

you musn’t skip this step or you will receive error when you try to connect to your database:

LOG: provided username (postgres) and authenticated username (uzer) don't match
FATAL: Ident authentication failed for user "postgres"

Oidentd used default configuration oidentd.conf, it should be in /etc/oidentd.conf, but I don't know why, on my local /etc, oidentd.conf doesn't exist. So, I need to create it by my self with

#nano /etc/oidentd.conf

and if fill it with :

default {
default {
deny spoof
deny spoof_all
deny spoof_privport
allow random_numeric
allow numeric
allow hide
}
}

user uzer {
default {
allow spoof
allow spoof_all
allow random
allow hide
}
}

I just add these lines to oidentd.conf but sorry, I can't explain anything about this, I can't get any other details except this.

Everything is set, now we are ready. Run Oidentd and postgresql services with this command in terminal :

#oidentd -C /etc/oidentd.conf
#service postgresql start

yapz.. that's all we need to used IDENT authentication method in POSTGRESQL and I am really looking forward your comment, especially about point six. Well, otherwise if you don’t to do the setup, you can just change the IDENT to md5 to save your time configuring POSTGRESQL. Thanks for reading anyway ... :)

Jet OleDb 4.0 and Office 12.0 Access Database Engine

2010-11-09T04:45:00.001-08:00

Have you ever found problem where you want to edit an office files (*.doc, *.xls, *.docx, *.xlsx) on dekstop without the Office application? yeah, I’m sure this is a common problem found by developers when their application trying to edit an office file on a server without (read : not allowed to install) Office installed on it? :P and I think nowadays still a lot of developers out there using interop / COM files in their program, unfortunately they can’t just install the COM objects without installing the office on the server.

Well, I suggest you to recode you application, change the codes from using COM object to System.Data.OleDb namespace. Trust me this would get around the licensing issue (read : don’t need to install the Office application) but still you need to makesure you have JetOleDb already installed for Office 2003 and Office 12.0 Access Database Engine for office 2007.

For Jet OleDb 4.0 actually already installed on OS XP, but if you found program failed due on OleDbCommand.Connection due to missing msjetoledb40.dll 2 ways around this:

Reduce your component visibilty, then the "Jet Database OLEDB Support"
compoent will come into view, and you can add it.
Copy the file "msjetoledb40.dll"
from a XP Professional (system32), and use "regsvr32" to register it.

You can find out more about Jet OleDb 4.0 from here and you can find out more about Office 12.0 Access Database Engine for office 2007 here.

Coder Girl Lyrics

2010-06-14T10:33:00.001-07:00

Coder girl, yeah I found this song several months ago.. I think it’s a good song for us, Programmer :D, enjoy!

Thank for DALECHASE, this is good :)

Coder Girl Lyrics:

to be the keys underneath her finger tips
Her class makes a brotha's back buffer wanna flip
and be number one on her link list
and get a callback, I'm in all caps
feels like my first hello world
what it is to run with a coder girl
and it ain't hard to like how she writes
with her pretty interface, plus her source is tight
wanna get in where I fit in like a plug-in
this is the true meaning of computer lovin'
She's got a data stack that's straight stunning
No mismatch, exceptions or debuggin
invariably, how would I pass this
when my coder girl grants me root access
basically, she's a certified A+
yo, it's more than just technolust

(chorus)

Feels like my first Hello World 'cause
She's my Coder Girl
Man, I had to dedicate this one
To my Coder Girl

I'll put it like this, so you can understand
She makes me wanna update to be a better man
When we compile she's easy to interpret
A cross-platform version I can work with
She's not wrapped in flash
all she wants is her java and a shell to bash
While, she's a sight to C, plus
Her smile glimmers just like a Ruby does
She could never be subroutine
The high priority process of my machine
Sharper than most chics ya' know
She's not another shallow copy actin' sudo
It's that good type dependancy
I function better with C.G. next to me
and it always leads to an overflow
When it's runtime and we take it slow

Setup AppSetting like .NET in JAVA

2010-06-13T10:08:00.001-07:00

Hufft… I felt really bothered when build an application in JAVA but I can’t have application configuration with global scope, customizable without recompiling code –___– when usually I got it easily when I build .NET application (which is app.config or web.config). Enough already!! :D So, I decided to create my own simple global configuration.. No more pain… no more sighhhhh hehehe :)) Created with XSD Schema and JAXB. Let’s go to the steps :

if you are using IDE Netbeans 6.8, you need “XML Schema and WSDL” plugin setup first. you can do it following this.
if you done with the first step, then create a new java application project, and add a XSD sample file to customize it as we need.

now we need to code the XML file configuration (AppSetting) and XSD Schema.

  1: <?xml version="1.0" encoding="UTF-8"?>
  2:
  3: <appSetting>
  4:     <setting name="CodeCount" serializeAs="String">
  5:         <value>1000000</value>
  6:     </setting>
  7:     <setting name="CodeCountTotal" serializeAs="String">
  8:         <value>2000000</value>
  9:     </setting>
 10:     <setting name="LettersCount" serializeAs="Integer">
 11:         <value>1</value>
 12:     </setting>
 13:     <setting name="NumbersCount" serializeAs="Integer">
 14:         <value>1</value>
 15:     </setting>
 16:     <setting name="Mix" serializeAs="Boolean">
 17:         <value>true</value>
 18:     </setting>
 19: </appSetting>
 20:

now the XSD Schema that following the XML file structure :

  1: <?xml version="1.0" encoding="UTF-8"?>
  2:
  3: <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  4:   
  5:     <xsd:annotation>
  6:         <xsd:documentation xml:lang="en">
  7:             AppSetting for Sample Application Setting.
  8:             Copyright 2010 CodeGear. All rights reserved.
  9:         </xsd:documentation>
 10:     </xsd:annotation>
 11:      
 12:     <xsd:element name="appSetting" type="ApplicationGlobalConfiguration"/>
 13:
 14:     <xsd:complexType name="ApplicationGlobalConfiguration" >
 15:         <xsd:sequence>
 16:             <xsd:element ref="setting" minOccurs="0" maxOccurs="unbounded" />
 17:         </xsd:sequence>      
 18:     </xsd:complexType>
 19:
 20:     <xsd:element name="setting" type="SettingType"/>
 21:
 22:     <xsd:complexType name="SettingType">
 23:         <xsd:sequence>
 24:             <xsd:element name="value" type="xsd:string" />
 25:         </xsd:sequence>
 26:         <xsd:attribute name="name" type="xsd:string" />
 27:         <xsd:attribute name="serializeAs" type="xsd:string" />
 28:     </xsd:complexType>
 29:
 30: </xsd:schema>
 31:

With JAXB we can generate the class persistence according the XSD Schema we have before. From window Project, add new JAXB Binding.

then It will create JAXB Binding in your project, right click > Regenerate java Code, to generate the java class persistence.

If you like, you can move the class persistence to your own package.

Now everything sets. To test it, I create simple code like this :

  1: package AppSetting;
  2:
  3: import com.conf.classpersistence.*;
  4: import java.io.File;
  5: import java.io.IOException;
  6: import java.util.List;
  7: import javax.xml.bind.JAXBContext;
  8: import javax.xml.bind.JAXBElement;
  9: import javax.xml.bind.JAXBException;
 10: import javax.xml.bind.Unmarshaller;
 11: /**
 12:  *
 13:  * @author tuta87
 14:  */
 15: public class Main {
 16:
 17:     /**
 18:      * @param args the command line arguments
 19:      */      
 20:     public static void main(String[] args) throws JAXBException, IOException {
 21:         JAXBContext jaxbContext = JAXBContext.newInstance("com.conf.classpersistence");
 22:         Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
 23:
 24:         JAXBElement<ApplicationGlobalConfiguration> appSettingElement =
 25:                 (JAXBElement<ApplicationGlobalConfiguration>)unmarshaller.unmarshal(
 26:                     new File("src/com/conf/xml/AppSetting.xml"));
 27:
 28:         ApplicationGlobalConfiguration appSetting = appSettingElement.getValue();
 29:         appSetting.setupHashtable();
 30:         System.out.println("Configuration count : " + appSetting.getSetting().size());
 31:         List<SettingType> listOfAllSetting = appSetting.getSetting();
 32:         for (SettingType setting : listOfAllSetting){
 33:             System.out.print("Setting Name :  " + setting.getName());
 34:             System.out.print(", DataType :  " + setting.getSerializeAs());
 35:             System.out.println(", Value :  " + setting.getValue());
 36:         }
 37:     }
 38:
 39: }
 40:

it will print out this to your console :

Configuration count : 5
Setting Name : CodeCount, DataType : String, Value : 1000000
Setting Name : CodeCountTotal, DataType : String, Value : 2000000
Setting Name : LettersCount, DataType : Integer, Value : 1
Setting Name : NumbersCount, DataType : Integer, Value : 1
Setting Name : Mix, DataType : Boolean, Value : true
BUILD SUCCESSFUL (total time: 1 second)

as you can see from the sample code on point five, all configurations saved in List<SettingType>. Now to make it more easier, I want all configuration putted in Hashtable<K,V> object. So it will makes clear about the data type every setting we have.

Open the ApplicationGlobalConfiguration.java, we need to add new Hashtable<K,V> property on it :

  1: package com.conf.classpersistence;
  2:
  3: import java.util.ArrayList;
  4: import java.util.Hashtable;
  5: import java.util.List;
  6: import javax.xml.bind.annotation.XmlAccessType;
  7: import javax.xml.bind.annotation.XmlAccessorType;
  8: import javax.xml.bind.annotation.XmlType;
  9:
 10: @XmlAccessorType(XmlAccessType.FIELD)
 11: @XmlType(name = "ApplicationGlobalConfiguration", propOrder = {
 12:     "setting","hashSetting"
 13: })
 14: public class ApplicationGlobalConfiguration {
 15:
 16:     protected List<SettingType> setting;
 17:     private Hashtable<String, Object> hashSetting;
 18:
 19:     public List<SettingType> getSetting() {
 20:         if (setting == null) {
 21:             setting = new ArrayList<SettingType>();
 22:         }
 23:         return this.setting;
 24:     }
 25:
 26:     public void setupHashtable(){      
 27:         List<SettingType> listOfAllSetting = this.getSetting();
 28:          for (SettingType setting : listOfAllSetting){
 29:              if (setting.getSerializeAs().equals("String"))
 30:                  this.getHashSetting().put(setting.getName(), setting.getValue());
 31:              else if (setting.getSerializeAs().equals("Integer"))
 32:                  this.getHashSetting().put(setting.getName(), Integer.parseInt(setting.getValue()));
 33:              else if (setting.getSerializeAs().equals("Double"))
 34:                  this.getHashSetting().put(setting.getName(), Double.parseDouble(setting.getValue()));
 35:              else if (setting.getSerializeAs().equals("Boolean"))
 36:                  this.getHashSetting().put(setting.getName(), Boolean.parseBoolean(setting.getValue()));
 37:           
 38:         }     
 39:     }
 40:
 41:     public Object getSettingValueByName(String settingName){
 42:         return (this.getHashSetting().get(settingName));
 43:     }
 44:
 45:     /**
 46:      * @return the hashSetting
 47:      */
 48:     public Hashtable<String, Object> getHashSetting() {
 49:         if (this.hashSetting == null)
 50:             return (hashSetting = new Hashtable<String, Object>());
 51:         else
 52:             return hashSetting;
 53:     }
 54: }
 55:

You need to pay attention on line :
Line 12 : add “hashSetting”, it according the property name on Line 17
Line 17 : add new property
Line 26 : a method used to setup Hashtable value and key
Line 41 : a method used to get a value by Setting Name
Line 48 : a method used to get the Hashtable object.

Now to test it you can do it with this sample code:

  1: boolean bl = ((Boolean)appSetting.getHashSetting().get("Mix")).booleanValue();
  2: String str = (String)appSetting.getHashSetting().get("CodeCountTotal");
  3: int i = (Integer)appSetting.getHashSetting().get("NumbersCount");
  4:       
  5: System.out.print("Try to get Mix value :  " + appSetting.getSettingValueByName("Mix"));

DONE! now i have my own AppSetting on my JAVA application. If you need the sample source of this post, you can take it from my DataBox. Enjoy… :)

fb:comments

2010-06-08T05:41:00.001-07:00

Hi guys!! Lately I found something more interesting then an ordinary Likes button, something that makes my blog more connected to the other network via facebook open graph it was facebook Comments. The way I implemented facebook comments on my blog, it’s not much different than facebook Likes button. After googling for a while, I found several related sources that describing about facebook comments i.e. here. :D * I feel weird when trying to pointing something with only word, when I usually use my hand :P. Ok, enough talk, lets go to the steps :

First, we need to create our own facebook application, you can do it here! from there, it will assist you to create your own facebook application.

Type your application name, and choose Agree radiobutton, then click Create Application.
Now, you can customize your application setting, the only things I did in this steps just choosing logo and icon for my facebook application, click Save Changes.

Finish, your application ready to use now.

We need to place an initialization facebook javascript sdk, then you need to set the application id (you can get it from first step)

<div id="fb-root"></div>
<script>
  window.fbAsyncInit = function() {
    FB.init({appId: 'your app id', status: true, cookie: true,
             xfbml: true});
  };
  (function() {
    var e = document.createElement('script'); e.async = true;
    e.src = document.location.protocol +
      '//connect.facebook.net/en_US/all.js';
    document.getElementById('fb-root').appendChild(e);
  }());
</script>

the last thing you need to do, put the <fb:comments/> tag on the place you want on your blog.
```
<fb:comments expr:xid='data:post.id' width='400'/>
```
This code only works for blog with blogger engine, where attribute xid indicates an unique id for every post I created on my blog.

Yapz!!! finish. Now I have my own facebook comments box on my blog :D

when I posted a comment on it, it will automatically putted on my news feed.

Nice and easy, isn’t it? :)

Facebook Open Graph (Update)

2010-05-21T19:22:00.001-07:00

Alright!! Here it is, guys. after several days, now I know how to implemented Facebook Open Graph on my blog. First of all, my blog engine is Blogger, so I think this not gonna work on another blog engine like Wordpress. The implementation is very, very, very simple. It was just adding some line on my blog code and taaddaaa!!! I have facebook Likes button on my blog.

Ok, Here we go :

First, open your blogger panel and choose edit layout, so you can take your blog layout code.

Add open graph and facebook namespace at the <html> tag as a xmlns, so it would be look a like :

  1: <html expr:dir='data:blog.languageDirection'
  2:  xmlns='http://www.w3.org/1999/xhtml'
  3:  xmlns:b='http://www.google.com/2005/gml/b'
  4:  xmlns:data='http://www.google.com/2005/gml/data'
  5:  xmlns:expr='http://www.google.com/2005/gml/expr'
  6:  xmlns:og="http://opengraphprotocol.org/schema/"
  7:  xmlns:fb="http://www.facebook.com/2008/fbml">

Then put this code on your head part :

  1: <b:if cond='data:blog.pageType == &quot;item&quot;'>
  2:  <meta property='og:title' expr:content='data:blog.pageName'/>  
  3:  <meta property='og:url' expr:content='data:blog.url'/>
  4:  <meta property='og:type' content='blog'/>
  5:  <meta property='og:site_name' content='Zouota Blog'/>
  6:  <meta property='og:image' content='http://www.freeimagehosting.net/uploads/37eeae1a93.jpg'/>
  7:  <meta property='fb:admins' content='zouota'/>
  8: </b:if>

Line 1, indicate that the loaded page was an item or a single blog post,
Line 2, og:title indicate the title of your blog post,
Line 3, og:url indicate you blog post’s url,
Line 4, og:type indicate it’s a blog.
Line 5, og:site_name indicate your Blog Name when it posted on facebook,
Line 6, og:image indicate your Icon for your blogpost when it posted on facebook,
Line 7, og:admins, here’s the important thing, indicating a facebook ID who will administering your pages (blog posts).
The complete reference about this, you can find it here!

At the beginning of <body> part I load facebook Java Scritpt SDK

  1: <script>
  2:    window.fbAsyncInit = function() {
  3:   FB.init({appId: &quot;<data:blog.url/>&quot;, status: true, cookie: true,
  4:      xfbml: true});
  5:    };
  6:    (function() {
  7:   var e = document.createElement('script'); e.async = true;
  8:   e.src = document.location.protocol +
  9:     '//connect.facebook.net/en_US/all.js';
 10:   document.getElementById('fb-root').appendChild(e);
 11:    }());
 12:  </script>

Everything are set. The last thing I need to do is adding facebook “Likes” element. well where you put it, it depends on your blog design.

  1: <div class='endpost'/>   
  2:  <b:if cond='data:blog.pageType == &quot;item&quot;'>
  3:   <fb:like width="450" height="20"/>
  4:  </b:if>
  5: </div>

There you are! when I open one of my blog post :

and when I login with my facebook account, it becomes look like :

when I click Admin Page, it’s redirecting me to the app.Admin page :

So guys, that’s what I do to add facebook Open graph on my blog post page, actually there are severl other thing I need todo to complete the update on facebook, like it said here!

If there's something I missed about this, please let me know and If you like my post about facebook Open Graph, there’s no other thing you need to do, except click my facebook “Likes” button :). Happy “Open Graph” all!

Facebook Open Graph protocol, why not :)

2010-05-20T09:49:00.001-07:00

Once upon a time, I saw “Likes” facebook button on someone blog, but I forgot who’s blog is it.. (damn… am I getting old already?) Then after I viewed Mark Zuckerberg facebook page, I read his status about f8 (facebook developer conference at San Francisco). When I saw inside that link, I found about Open Graph Protocol (The Open Graph protocol enables you to integrate your web pages into the social graph. It is currently designed for web pages representing profiles of real-world things — things like movies, sports teams, celebrities, and restaurants. Once your pages become objects in the graph, users can establish connections to your pages as they do with Facebook Pages.)

It mean that all of my blog posts on this page can be an object in the graph… hehehehe isn’t it interesting?

Here we go! to turn on my blog post into graph objects, I need to add Open Graph protocol <meta> tags and the likes button on my blog post pages. Firtst time I got confused, because the example only for single specific web page, what about if I want to placed “likes facebook button” below on every blog posts I have made and each of it specific for each blog posts. hmmm searching.. searching.. searching.. great! I’m stuck :D I’ll back to this topic ASAP when I found the clue.. so see you later ;)

Read Linux Partition (ext2/ext3/ext4) on Windows 7

2010-05-16T01:44:00.001-07:00

My laptop using Dual Boot system, I’ve installed Microsoft Windows 7 and Linux Fedora 12. Sometimes it really bother me, when I must restart my Windows to get data from my Linux operating system. Well.. not anymore, cause now I used program called Ext2Fsd, it mount all of my linux partition (ext2/ext3) into regular drive in windows explorer, so I can copy and paste all of my data from and to my Linux operating system.

Here, the steps :

Download the Ext2Fsd here.
Right click on downloaded file then choose Properties, on tab Compatibility make the Compatibility Mode to Windows Vista Service Pack 2
Run the installer as an Administrator.
During installation, it will ask you to choose enabled write access feature, If you trying against loosing data in your linux partition, uncheck it. Don’t worry, cause you can change the configuration after installation when you need it.
Run Ext2.

as you can see, Ext2 has listed my Linux Partition, everything you need to just start the service :

Right click on linux partition and choose Service Management or press F7
Click button Start to start the service, you can see that on the third line already assigned drive letter J:/
When I open my windows explorer, it will be my Linux Drive data.
On “service startup mode” part I rather choose it SERVICE_DEMAND_START, because I only want it started when I want it.
Like I told you before, that you can chage the write access, it’s on “Global Volume Setting”.

Then for the ext4 partition file system, I found it here! He said that the only way you can read you Linux Operating System data with ext4 partition file system, is when you create the partition you must create regular Ext4 file system drive then run command :

mkfs.ext4 -j -O '^extent' -L 'YourLabel' /dev/sda2

Used Ubuntu 9.10 live CD for that, and replace /dev/sda2 with your own drive.

WLW Source Code Plugin

2010-05-15T21:50:00.001-07:00

Windows Live Writer Source Plugin.. yeah.. that’s one of my favorite plugin.. with this plugin I can copy and paste my sample code to this blog nice and easily :P.

I got this plugin from here ! Below is the java sample code that I was generated with this plugin.

  1:  List<TrainSchedule> lTrainSchedule = trainScheduleController.findTrainScheduleEntities("Pocin4");
  2:         for (TrainSchedule tsTest : lTrainSchedule){
  3:             System.out.println("Station Name: " + tsTest.getStrStation() );
  4:             System.out.println("Train Name: " + tsTest.getStrTrainName() );
  5:             System.out.println("Train Type: " + tsTest.getStrTrainType());
  6:             System.out.println("Time : " + tsTest.getDtSchedule().toString());
  7:             System.out.println("");
  8:         }
  9:         System.out.println("Jumlah : " + Integer.toString(lTrainSchedule.size()));

As you can see, there’s a lot of functional options to formating our sample code like :

Language : ASPX, C, C#, C++, COBOL, Cold Fusion, CSS, Eiffel, Fortran, Haskell, Java, JavaScript, JScript, Mercury, MSIL, Pascal, Perl, PHP, Python, Ruby, SQL, Visual Basic, Visual Basic Script, XML
Box
Alternate Line Colors, and
Selection Code

MySQL Workbench

2010-05-15T17:00:00.001-07:00

First time used MySQL Workbenc on my Win7, it's more suitable for me... everything in 1 form, it provides DBAs and developers an integrated tools environment for :

Database Administration (replacing MySQL Administrator)

SQL Development (replacing MySQL Query Browser)

Database Design & Modeling

some steps I took to install MySQL Workbench :
I used "yum" command to install it from "remi" repo, so :
    # wget http://rpms.famillecollet.com/remi-release-12.rpm
then execute downloaded rpm file with :
    # rpm -Uvh remi-release-12.rpm
the last, install the workbenc with command :
    # yum --enablerepo=remi install mysql-workbench

if you saw this in your terminal, then your MySQL workbench is ready to use!

Start GlassFish v3

2010-05-14T20:20:00.001-07:00

When I tried to start my glassfish v3 domain, and tried to open my console, I got this :

HTTP Status 404 - /login.jsf not found

then I realize that I start the glassfish domain v3 from Netbeans 6.8, when I tried to start glassfish domain from linux terminal or windows console with :

linux terminal :

./asadmin start-domain --verbose domain1

windows console :

asadmin start-domain --verbose domain1

I find my login page :P

is there anyone know why this could be happen?

Tigah

2010-02-01T05:52:00.001-08:00

Huuaaaaa… dah lama banget gw gak apdet ne blog..

Banyak yang terjadi selama 1 semester gw kuliah di UI, mulai dari dapet temen baru, pacar baru (gak jelas ceritanya sekarang gmana [-( ), sampe musuh baru hahahahaha (like I care :P)

Dipostingan ini gw mau ceritain soal perjalanan gw ke bandung dengan temen baru gw … dia baik , gak banyak omong, terus mau nemenin gw kemana aja. Let me introduce you to TIGAH. Kendaraan bermotor roda dua Honda Tiger 2006 Black CW. Sekarang jadi partner buat kerja, kuliah, pulang hehehehe… Alhamdulillah akhirnya bisa ninggalin rutinitas naik angkot dan metromini *jadi keinget sesuatu :

Di seruduk angkot dari belakang di pasar minggu ampe ampir nyungkur di jalan (dasar STUPID BLIND Angkot Driver hahahahhaha >J) *istighfar.. astaghfirulllahhhh….
Niat hati yang baik bantuin dorong kopaja 57, alhasil dibalas dengan semprotan asap hitam kenalpot kopaja yang super ngebul (F*CK) dan tragisnya gw di tinggal jalan gitu aja ma sopirnya *hikss hiks… (dasar kopaja Driver gak punya nurani hahahahhaha >J) *istighfar.. astaghfirulllahhhh….
Naik metromini 75 di pasar minggu pas bulan puasa baru naik 10 meter dah mogok dia, supir noleh ke belakang dan penumpang laki-laki yang tampan dan baik hati di situ cuma gw doang (hiehehehehehe :P) tuh supir natap gw dengan tatapan penuh harapan, kembali dengan alasan niat hati yang baik gw dorong tuh metromini.. (NOTE : gw dorong metromini itu SENDIRIAN karena tu metromini keneknya anak umur 10tahunan, jam 4 sore dibulan puasa ) Alhamdulillah metromini bisa gw dorong sampe 20KM hmm… maksudnya 20M hehehehe soalnya gw dah keburu tepar di pinggir jalan (Dehidrasi ceritanya @___@) dan keadaan semakin membaik setelah metromini itu tetep gak bisa jalan dan gak ada yang nolong terus bilang gw orang gila karena ngegelepar di pinggir jalan.. (NICEEEEE!!!)

Haaaaaa.. sekarang.. semoga masa-masa itu gak terulangi lagi, karena sudah punya partner jalan-jalan yaituu TIGAH.. (hmmm ini ttg perjalanan ke bandung atau perjalanan kesengsaraan yaa..??) gak papa, 2 cerita di rapel aja. :D

Mendengar cerita temen-temen yang katanya asik bener perjalanan ke bandung melalui puncak dengan motor yang memakan waktu 2 jam, gw jadi pengen cobain sekalian jajal kemampuan Tigah. Akhirny membulatkan tekat untuk brangkat pagi hari jam 07.30 sepanjang jalan gak ada yang menarik selain jalanan puncak yang menikung tajam dan sepi, hehehehe jadi kesempatan buat praktekin cara cornering yang gw dah baca-baca di internet selama ini.. alhasil karena ragu dengan kemampuan traksi ban si Tigah, jadi 2 kali keluar jalur jalan kerena ragu buat rebah ketika nikung terutama tikungan ke kanan. Kenapa ya?? But, not bad for beginner like me :D hmmm setelah 2 jam perjalanan, hati mulai bingung :D, kenapa gw belum sampe bandung juga ya? Apa nyasar ini? Setelah tanya-tanya orang di jalan, katanya jalurnya dah bener, akhir perjalanan sampe bandung dalam waktu 3.5 jam(cerita gak semanis kenyataan T___T, but that was really fun :)).

Perjalan balik ke depok, gw mulai dari jam 14.15 (berdasarkan pengalaman sebelumnya pasti sampe magrib) di tambah lagi sepanjang jalan hujan , ternyata bener aja, di jalan raya puncak macet parah. Sampe akhirnya jalan di jadiin satu arah. Alhasil sampe depok kucel gak karuan mulai si Tigah, gw, sama sepatu somplak kesayangang :D

Hmmm dengan kecepatan rata 80Km/Jam gw butuh waktu sekitar 4jam dan itu udah dengan salip sana dan sini. Apa seharusnya bisa lebih cepat atau emang udah wajar segitu ??

hmm.. Next time, gw mo cerita ttg HTML :)

IT to IS

2009-07-27T07:02:00.001-07:00

Ok.. tulisan ini berhubungan ketertarikan gw tentang Sistem Informasi (jurusan yang gw ambil sekarang). Sekedar mulai cari tau sebenernya apa yang akan gw pelajari dan apa bedanya dengan jurusan Teknik Informatika yang sebelumnya gw ambil di DIII. Ditulisan ini mungkin gw coba buat explore lebih spesifik ke bagian Sistem Informasi.

Sistem Informasi atau Information Systems (or computer-based information system), maknanya sendiri dapat kita gambarkan dari sebuah software yang spesifik untuk menyimpan data (record) serta melakukan otomatisasi untuk beberapa jenis pengolahan data. Hal ini merupakan bagian dari Teknik Infromatika, kemudian bagaiman bentuk dari pengolahan (business process modeling) yang menjelaskan bagaimana business process tersebut di bentuk adalah bagian dari Sistem Informasi.

Sistem Informasi memiliki peranan penting dalam design, control, support serta pengembangan dari business processes dan Teknik Informatika yang akan mengimplementasikannya. TI dan business processes adalah bagian yang tidak dapat di pisahkan maka dibutuhkan keahlian dalam business information systems, kerena jika terjadi kesalahan dalam pengorganisasian dari sistem informasi akan mengakibatkan kesalahan fatal sehingga terjadi penghentian development.

Dari kedua gambar di atas jelas sekali mengenai pembagian kerja dari Sistem Informasi dan Teknik Informatika, dimana SI harus benar-benar menguasai setiap bagian dari sistem dan permasalahan serta solusinya. Sedangkan TI harus lebih menguasai teknologi guna implementasi business processes dan solusi setiap permasalahan.
Sekarang gw mau tambahin beberapa pembagian dari sistem informasi berdasarkan pembagian kerjanya, tapi sorry soalnya gw tulis pake bahasa inggris yang langsung copy paste dari sumbernya.
Karena gw takut maknanya jadi salah, maklum bahasa inggris gw pas-pasan hehehehe

Classification of System Information :

Transaction processing systems(TPS) automate the handling of data about business activities or transactions, which can be thought of as simple, discrete events in the life of an organization. Data about each transaction are captured, transactions are verified and accepted or rejected and validated transactions are stored for later aggregation.
A Management information system (MIS) is a subset of the overall internal controls of a business covering the application of people, documents, technologies, and procedures by management accountants to solve business problems such as costing a product, service or a business-wide strategy
Decision Support Systems (DSS) are a specific class of computerized information systems that supports business and organizational decision-making activities. A properly-designed DSS is an interactive software-based system intended to help decision makers compile useful information from raw data, documents, personal knowledge, and/or business models to identify and solve problems and make decisions.
An expert system is software that attempts to reproduce the performance of one or more human experts, most commonly in a specific problem domain, and is a traditional application and/or subfield of artificial intelligence.
Business intelligence (BI) refers to skills, technologies, applications and practices used to help a business acquire a better understanding of its commercial context. Business intelligence may also refer to the collected information itself.

hmmm sampe saat ini, baru segini yang gw dapet. mungkin kalo ada temen-temen yang ingin menambahkan atau mungkin koreksi terhadap tulisan ini. I'll really appreciate that :)

Grow Up

2009-05-12T08:56:00.001-07:00

Akhir-akhir ini banyak sekali pelajaran yang gw dapet... banyak sekali hal-hal baru yang gw temui... Bingung mau ngomong apa di sini...

Hari ini cukup di kagetkan dengan berita dari boss di kantor, karena beliau memutuskan resign dari kantor... so sad... karena baru sedikit hal yang gw pelajari dari beliau, tapi ya seperti beliau bilang "that's life, dimana lo gak bisa tebak apa yang lo jalanin di masa depan..." alasan beliau mengundurkan diri karena beliau ngerasa dapet tantangan baru dan itu bukan dari bidang yang selama ini beliau geluti (IT Engineer as Departement Head of Telco and Brain). Beliau termasuk orang yang memiliki posisi tinggi disini dan bukan hal yang mudah untuk bisa mendapatkan posisi tersebut di perusahaan ini, orang yang duduk pada posisi tersebut adalah orang yang benar-benar full skilled, qualified serta professional di bidangnya.

Beliau bercerita bahwa tantangan baru yang dia dapatkan adalah pada perusahaan swasta lain yang bergerak di bidang jasa asuransi. Can you imagine this?? It doesn't make senses for me.... ditambah lagi pekerjaan yang beliau akan masuki bukan sebagai karyawan di perusahaan tersebut, tapi sebagai agent dari perusahaan tersebut. Beliau mengatakan ini wajar karena jika beliau berada pada posisi saya, pasti beliau juga akan berfikiran hal ini tidak masuk akal. Beliau mengatakan karena dunia ini benar-benar baru dan menantang untuk di masuki, dan suatu saat saya pasti mengerti.

Hehehe.. tawa kagum bercampur tanya...

Beberapa nasehat yang beliau sampaikan, mungkin ini baik untuk semua :

Be struggle, berjuang keras.. jangan pernah terlena dan cepat merasa puas dengan apa yang kita dapat sekarang. karena akan ada saatnya dimana kita akan menikmati setiap kerja keras kita dimasa muda. Jika kita mendaki sebuah gunung dan orang berkata akan mengalami kesulitan, menemui jalanan terjal, batu dan kerikil. Itu benar, tapi bukan hal jadi alasan untuk mendaki gunung tersebut setengah-setengah bahkan mengurungkan niat mendaki gunung tersebut. Fight... Berusaha sekuat tenaga, capai puncak gunung tersebut sehingga kau bisa liat apa yang ada di atas sana dan nikmati. Jadi gak hanya menikmatinya dari bawah saja.
Cobalah untuk dapat lebih mengerti orang lain, hal ini sangat penting dalam membangun relasi kita dalam kehidupan sehari-hari kerja.

U ntuk point ke dua, hal ini yang mungkin lebih berat. Membangun karir di tengah-tengah orang yang cuma mau tau dan peduli dengan bagian mereka.. sulit karena gw termasuk tipe orang yang gak suka dengan orang yang seenaknya dan belagu. It's not an easy stuff... but I'll try.. :) dan cuma satu kalimat yang bisa terucap dari bawahan culun dan keroco ini "OK... Semoga sukses pak..." hehehe

Well... ini mungkin point dimana gw harus belajar untuk lebih dewasa dalam menghadapi setiap persoalan, gak perlu dengan ngotot dan emosi, just show them how great you are from what you have done. Just like my syster said "your works credibility only can perceptible from your job result!!!"

Next Opinion...

2009-04-17T17:39:00.001-07:00

Karena saya merasa belum dapat jawaban konkrit pada pertanyaan sebelumnya, maka saya coba pertanyakan lagi dengan hal yang lebih spesifik dan Topik baru
Bisa gak kalo IT Center di kepengurusan yang sekarang Prokernya cuma ikut event-event kompetisi..? Jangan bebani IT Center dengan pekerjaan lain (i.e. ngadain seminar atau workshop, karena ini lebih cocok sebagai kerjaannya Akademik... bener gak sih??)
Kekurangan yang kurasakan dulu adalah... IT Center tuh gak tau musti gmana dan ngapain... selalu aja ngikutin yang sudah-sudah...
Mulai sekarang......

Coba biarkan IT Center untuk melihat seperti apa perkembangan himpunan maupun kehidupan mahasiswa IT di kampus lain secara real melalui ciptaan mereka di event tersebut....
Coba biarkan IT Center konsentrasi dengan ngebentuk Tim-Tim khusus untuk ikut event Kompetisi...
Coba biarkan IT Center untuk dapat mengubah orang-orang berkompetensi menjadi orang-orang geek akan pengetahuan teknologi...
Coba biarkan IT Center untuk membawa nama Himpunan dan Almamater keluar pada event kompetisi...
Coba biarkan IT Center untuk dapat menuliskan nama HIMA IF Universitas Padjadjaran... (paling gak di daptar peserta ... PEACE ahh... )

Ok ini cuma gambaran yang seharusnya dapat saya lakukan sedianya dahulu kala... apa daya dan upaya karena terlambat menyadari hal ini maka tidak semua dapat terlaksana....
Sekali lagi sodara-sodara... ini cuma pertanyaan dan opini saja... tapi tolong sodara-sodara... tolong di ilhami dengan cermat dan teliti, dengan hati ikhlas, dengan kebulatan tekad, dengan kesungguhan hati, dengan pengorbanan jiwa dan raga demi perjuangan para pahlawan kitaaaaaa MERDEEKKAAAAAHHHHH....
krik.. krik.. krik..

Sekarang jika di tanya apa yang bisa di lakukan untuk mencapai hal tersebut, well... there's several things we can do...

caranya membentuk kelompok belajar (bentuk kelompo k kemudian tinggal bagi tugas untuk membahas satu Ebook atau bacaan apapun, jadikan diri sendiri mentor untuk teman-teman, dan jangan bergantung pada teman untuk bisa belajar sesuatu dan tidak saya pungkiri kalau sering membutuhkan teman yang tidak di minta pun mau share knowledge )
dalam cara belajar (i.e. tidak tau mengenai sesuatu pada teknologi tertentu, jangan langsung tanya pada orang atau forum tertentu, karena sering kali mudah di temukan di search engine) karena yang saya lihat lebih banyak bertanya dari pada mencari
kembali lagi ke point yang saya sebutkan sebelumnya... Pasti mereka juga seharusnya bisa belajar manual sendiri (dari sisi teknologi) kemudian untuk mentor.... ini menurut saya yang agak janggal... karena mentor yang mereka inginkan adalah yang bantuin mereka belajar ini dan itu... padahal mentor di sini seharusnya yang ngarahin mereka musti apa dan bagaimana...

the point is.... be autonomous and learn by doing...

Just Sugestion...

2009-04-11T17:39:00.001-07:00

hhhmmmm.....
saran aja ne ya... Bisa gak pengurus tahun ini konsentrasinya gak cuma seminar-seminar doang?
Coba lebih diarahkan konsentrasinya untuk mengikuti event-event kompetisi a.k.a IMAGINE CUP 2010?
ya gak cuma ImagineCup aja kok, kompetisi IT yang lain jg banyak kan?
soalnya kalo di suruh bikin seminar-seminar doang, saya pribadi percaya kalian pasti bisa berhasil melaksanakannya.
tapi untuk bisa ikut dan kalo syukur2 bisa menang itu hal yang lebih baik. Dampak untuk ke himpunan sendiri juga pasti lebih besar kok dari pada ngadain seminar.

Karena analoginya seperti ini :
Kalian ngadain seminar itu artinya kalian mendemokan sebuah teknologi (i.e .NET) ataupun cara untuk melakukan sesuatu dengan teknologi tertentu (HACK dengan LINUX), ini hanya akan menaikkan popularitas dan harga jual teknologi tersebut (believe me... tetep aja kita tuh akan masuk peta perkembangan Teknologi) dan juga efeknya jangka pendek (bahkan 3 dari 10 peserta bisa di jamin kalo gak tidur paling kerjain yang lain kalo ternyata acara yang mereka hadiri gak sesuai dengan ekpektasi mereka)
tapi...
Kalo kalian ikut event dan syukur2 bisa menang... well yang naik popularitas dan harga jual adalah kalian pribadi peserta lomba, himpunan, dan ALMAMATER . Ini efeknya jangka panjang. Ini akan memberikan dorongan dan semangat buat rekan-rekan angkatan selanjutnya.

Nah, sekarang kalo masih ngotot untuk ngadain seminar. Ini saranku... Menurut ku pribadi sih ngadain seminar atau workshop itu ada 2
- Buat cari duit dan glamouritas
- Buat sharing ke sesama rekan di bidang IT

Kalo pilihan kalian yang pertama (cuma mikirin duit...duit...duit... dan glamouritas) do what ever you want, I DON'T CARE....
Kalo pilihan kalian yang kedua, berusahalah sampaikan materi yang lebih ke arah teknikal pembuatan (i.e bagaimana design UI yang friendly dengan Silverlight) bukan ke arah penggunaan (i.e materi bagaimana mengunakan WINDOWS 7). kemudian usahakan kegiatan tersebut free, karena level penguasaan IT di kampus kalo munurut saya masih di bawah 5 (berdasarkan hasil perbandingan saya pribadi dengan jurusan-jurusan IT di kampus lain). Nanti bisa keliatan mana yang anak yang punya passion di bidang IT dan mana yang tidak (lah... di suruh ikut kegiatan gratis aja gak mau coba... what's on earth)
Sekali lagi ini cuma saran dan pendapat aku pribadi, jadi kalo menurut kalian gak masuk akal yah... Just think this is just a crap.

2009-03-20T00:41:00.000-07:00

try to post something for the first time here....
