转贴：以上是一个示例程序，下面是程序简介。
JAVA系统托盘图标控制程序说明：
　　这是一个用Java JNI技术写的系统托盘图标控制程序．暂时还是一个测试版本，带有一个显示我的mail信息的对话框．
配置和运行：　
　　该程序运行于JDK1.3以上，首先你的机器必须支持在DOS窗口下直接输入java运行jar文件，如果不行，请在sun公司的网站java.sun.com进行JDK的最新版的下载和安装．
　　通常你可以直接双击TrayIconTest.jar运行本程序，如果不能直接双击运行，请使用run.bat文件运行.

Answer 5

这个程序我试过了,在运行
staticInstance.initTrayIcon(staticInstance,"JavaTrayIconApp",1000);的时候出错,我已经和作者联系过了,
还在等待回音.....

Answer 6

有没有人用这个成功过啊（不是用demo，而是自己新建一个工程，把trayIcon加进去！）？？？我运行下面这句的时候出错！！
staticInstance.initTrayIcon(staticInstance,"JavaTrayIconApp",1000);错误为UnsatisfiedLinkError
