ANT build script for LWUIT blackberry application

Update:
  This article is more than a year old, now LWUIT project uses a new tool to build BlackBerry application - NetBeans BlackBerry Plugin, please refer my two latest post:

  Developing Blackberry application using NetBeans Plugin - part 1, first impression
  Developing Blackberry application using NetBeans Plugin - part 2, fixing debug issue


Shai's article about build script for LWUIT in BlackBerry is great, but it has so many errors,I spend two days trying to fix the errors, and finally make it work.

Here I posted my modified ant buil.xml and application source code. The application is very simple, just display a "Hello World" text. Since this article is based on Shai's article, for details such as project set up, configuration and tools installation etc, please check his article.

application source code
HelloLWUITMidlet.java

import com.sun.lwuit.Display;
import com.sun.lwuit.Form;
import com.sun.lwuit.Label;
import com.sun.lwuit.layouts.BorderLayout;


public class HelloLWUITMidlet extends
//#ifdef RIM
     net.rim.device.api.ui.UiApplication
//#else
//#      javax.microedition.midlet.MIDlet
//#endif
 {
    public void startApp() {

        Display.init(this);
        Form f = new Form();
        f.setTitle("Hello World");
        f.setLayout(new BorderLayout());
        f.addComponent("Center",
        new Label("I am a Label"));
        f.show();

    }
//#ifdef BlackBerry
   public static void main(String[] argv)
   {
       new HelloLWUITMidlet().startApp();
   }

   public void notifyDestroyed()
   {
       System.exit(0);
   }

   public void platformRequest(String s) {
      net.rim.blackberry.api.browser.Browser.getDefaultSession().displayPage(s);
     }
//#endif


    public void pauseApp() {
    }

    public void destroyApp(boolean unconditional) {
    }
}

Note:
This build script is for touch screen build, for non touch sreen build you need to
1.Comment out "bbtouch" property in target "post-init" :
<!-- <available file="${platform.home}/simulator/9500.bat" property="bbtouch">  --> </available>
2.Remove the "copyBBTouchSources" dependency in target  "bbbuild".
