Question

eclipse中的J2ME程序保存出错

import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Form;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;

public class Frist extends MIDlet {
private Form form;

public Frist() {

form = new Form("第一个MIDlet");
form.append("欢迎进入J2ME世界 ");

}

protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
// TODO Auto-generated method stub

}

protected void pauseApp() {
// TODO Auto-generated method stub

}

protected void startApp() throws MIDletStateChangeException {
// TODO Auto-generated method stub
Display.getDisplay(this).setCurrent(form);
}

}
这是保存时出现的错误
Errors occurred during the build.

我想问下这是怎么回事，是配置的问题吗？
这个是我eclipse的设定

Answer 1

你的程序没错，我在我的机子上运行了下。代码没错，你是不是配置有错啊。安装EclipseMe了吗？开发Me要安装这个插件。

Answer 2

1，你设好环境变量了吗？
2，你用的那个环境（IDE）环境与jdk是否绑定。
3，你安装插件了吗？

Answer 3

重新建下工程 重新打包jar
