              你可以将以上代码保存在WEB服务器上，例如保存为text.wml

3、 修改jad文件：

在jad文件中增加

MIDlet-Jar-URL: http://domain/directory/test.jar

其中的http://domain/directory/test.jar为你的jar文件的路径。

       经过上面的设置，你就可以将你的wml页面路径作为你的WAP下载页面发布了。用户只需要在手机上输入这个路径就可以访问和下载你的程序了。

public synchronized void go() {
notify();
}

这样效率比较高了！当用户进行联网操作的时候我们应该做一个提示界面，比如一个动画告诉用户正在进行联网操作。这样比较友好。那么当用户选择联网动作的时候，我们让我提前做好的欢迎界面显示在屏幕上，联网结束后再把返回的结果显示出来。这样就是一个出色的联网应用程序了。下面的这个代码可以在屏幕上描绘一个动画的效果，当然你也可以修改一下做成自己喜欢的样子。
