在netbeans中運行j2me應用程序時出現問題

Question

我對j2me非常陌生。我創建了一個示例程序，但我無法運行該程序。構建失敗的消息來了。我的代碼是：

import javax.microedition.lcdui.*; 
import javax.microedition.midlet.*; 

/** 
* @author aneesh 
*/ 
public class httpconnection extends MIDlet { 
    private Command exit, start; 
    private Display display; 
    private Form form; 
    public httpconnection() 
    { 

    } 
    public void startApp() { 
    display = Display.getDisplay(this); 
    exit = new Command("Exit", Command.EXIT, 1); 
    start = new Command("Start", Command.EXIT, 1); 
    form = new Form("Http Connection"); 
    form.addCommand(exit); 
    form.addCommand(start); 

    display.setCurrent(form); 
    } 

    public void pauseApp() { 
    } 

    public void destroyApp(boolean unconditional) { 
    } 


} 

，我得到的錯誤是

java.lang.UnsatisfiedLinkError: /usr/local/netbeans-7.0/mobility/WTK2.5.2/bin/sublime.so: /usr/local/netbeans-7.0/mobility/WTK2.5.2/bin/sublime.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

Answer 1

好像你有32位WTK和64位JDK。您應該安裝匹配的32位JDK並設置WTK以使用它。

從Sun（Oracle）網站下載的命令行WTK安裝程序應在安裝期間要求您提供JDK位置。
