出错的代码段为：

415处：
//move mouse out of the applet and back
try {
Robot rb = new Robot();//415
rb.mouseMove(0, 0);
rb.mouseMove(mouseX, mouseY);
} catch(AWTException e){
e.printStackTrace();
}


870处：
public void init() {
goodsPanelInit();
tableInit();
scrollPanelInit();
panelInit();//870

}

大哥大姐帮我看看，这个是怎么回是啊？

没太看明白，你是在哪执行的，JB，还是命令行。

写清楚点，这谁能看懂啊！
问问题也要有点诚意啊！

不好意思，是这个样子的。
服务起端是jboss+linux+mysql
客户端是win2000的。

上面是个applet，然后在jsp中调用。
我在本机浏览时，applet报上面的错误。

由于程序太长，所以没贴出来。
大家可以帮我分析一下是什么原因出着这个错的吗？


刚才我在本机，用eclipse调试了这个applet，没有报错，可以运行。
不知道这是什么回事？
