我对 j2me 很陌生。我创建了一个示例程序，但我无法运行该程序。构建失败消息来了。我的代码是：

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) {
    }


}

我得到的错误是

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)

好像你有 32 位 WTK 和 64 位 JDK。您应该安装匹配的 32 位 JDK 并设置 WTK 以使用它。

从 Sun (Oracle) 网站下载的命令行 WTK 安装程序应该会在安装过程中询问您的 JDK 位置。
