Exception in thread "AWT-EventQueue-0"
在做个抓包+分析的简单软件，图形用户界面能出来了，但是一按“开始监听”就弹出了这一大串错：

从字面上看是找不到jpcap库，可是我已经把wincap装上了，jpcap.jar、jpcap.dll也放对位置了，怎么会这样。。

------解决方案--------------------
要把那些DLL文件所在目录加到PATH环境变量中。
------解决方案--------------------
代码不完整。

现在还是看不出哪里有问题。。
------解决方案--------------------

探讨

我用MyEclipse做开发工具的，是写在.classpath文件下么？
