J2ME的代码从Eclipse拷入Jbuilder2005中运行不出来
我这里有一个J2ME的代码,在Eclipse4.2里可以模拟出来.因为种种原因,我想把它移植到Jbuilder2005中去,于是在Jbuilder中新建一个工程及相关Java类,将代码拷入,代码没有报错,但在模拟器里出不来,请各位大虾指教如何是好?谢谢
觉得Eclipse和Jbuilder的Midlet和Convas文件相当不一样.(其它的Java的文件应该差不离)

被覆盖的Jbuilder 的代码:

MineMidlet.java文件:
package mine;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
public class MineMidlet extends MIDlet
{
  static MineMidlet instance;
  MainCanvas displayable = new MainCanvas();
  public MineMidlet()
  {
  instance = this;
  }

  public void startApp()
  {
  Display.getDisplay(this).setCurrent(displayable);
  }

  public void pauseApp()
  {
  }

  public void destroyApp(boolean unconditional)
  {
  }

  public static void quitApp()
  {
  instance.destroyApp(true);
  instance.notifyDestroyed();
  instance = null;
  }

}


MainConvas文件:
package mine;

import javax.microedition.lcdui.*;

public class MainCanvas extends Canvas
{
  public MainCanvas()
  {
  try
  {
  jbInit();
  }
  catch(Exception e)
  {
  e.printStackTrace();
  }
  }

  private void jbInit() throws Exception
  {
  // add the Exit command
  addCommand(new Command("Exit", Command.EXIT, 1));
  }

  protected void paint(Graphics g)
  {
  /** @todo Add paint codes */
  }
}

原Eclipse代码
MineMidlet.java文件:
public class MineMidlet extends MIDlet {
  private static MainCanvas m_MainCanvas;  
  public static MineMidlet m_Midlet;
  public MineMidlet() {
  super();
  m_Midlet = this;
  }
  protected void startApp() throws MIDletStateChangeException {  
  try{
  m_MainCanvas = new MainCanvas();  
  }
  catch (Exception ex){ } 
  Display.getDisplay(this).setCurrent(m_MainCanvas);
  }
  protected void pauseApp() {
  m_MainCanvas.Stop();
  }
  protected void destroyApp(boolean arg0)throws MIDletStateChangeException {
  m_MainCanvas.Stop();
  }
}

MainConvas文件:
package mine;
public class MainCanvas extends GameCanvas implements Runnable{
  public MainCanvas( ){
  super(false);
  try{ 
  }
  catch(Exception exception){} ;
  Start();
  }  
  public void Start(){
  m_bRunning = true;
  Thread thread = new Thread(this);
  thread.start();
  }
  public void run() { 
  }
   
  public void Stop(){
  m_bRunning = false;
  }
  public void Input(){
 
  }
  public void Logic(){
  }
  public void Paint(){
  Graphics g = getGraphics();  
  }  
   
}
