解决了此问题才算是高手！！！（高分结贴）

一个web层程序，不如简单的登陆窗口，登陆之后，将用户的信息存于cookie或session当中，

然后从浏览器，采用webstart的方式，点击一个jnlp链接，启动GUI程序，也很简单，比如一个frame中内置一个文本框，
请问，GUI程序是否能够访问在web界面中保存的cookie或session信息,能否给个例子
（我还有一个附加的问题：对于web start技术，我看了"轻松玩转Java Web Start"
这篇文章，可以用google收到，试验之后，也成功了，不过对里面的JCE相关技术，知识不是很能够理解，各位大侠，给小第一个提示）。
