1. 安装BlackBerry_Email_MDS_4.1.4.exe和BlackBerry_Simulators_5.0.0.228_9700.exe

2. 安装eclipse3.6

3. 安装BlackBerry Java Plug-in for Eclipse v1.1

4. 创建BlackBerry工程，File -> New -> Project -> BlackBerry -> BlackBerry Project

  Project name: HelloWorld

  Click "Finish" 完成项目创建

5. 创建一个新的java类，名称为HelloWorld，内容如下：

 

import net.rim.device.api.ui.Field; import net.rim.device.api.ui.UiApplication; import net.rim.device.api.ui.component.Dialog; import net.rim.device.api.ui.component.LabelField; import net.rim.device.api.ui.component.RichTextField; import net.rim.device.api.ui.container.MainScreen; public class HelloWorld extends UiApplication { public static void main(String[] args) { HelloWorld theApp = new HelloWorld(); theApp.enterEventDispatcher(); } public HelloWorld() { pushScreen(new HelloWorldScreen()); } } final class HelloWorldScreen extends MainScreen { HelloWorldScreen() { super(); LabelField title = new LabelField("Hello World Title", LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH); setTitle(title); add(new RichTextField("Hello World!", Field.NON_FOCUSABLE)); } public void close() { Dialog.alert("Goodbye!"); super.close(); } }  

 

6. 在BlackBerry的模拟器中运行HelloWorld程序

  选择HelloWorld项目，右键 -> Run As -> BlackBerry Simulator

  在出现的BlackBerry Simulator窗口里单击菜单按钮，然后单击Downloads图标，此时会出现刚刚新建的HelloWorld应用程序的图标，单击此HelloWorld图标就可以运行此应用程序，这个HelloWorld程序就是在应用程序窗口里显示一个HelloWorld的标签。
