上面的程序是JEditor对象显示URL资源，导入的类这儿被我省了，运行程序时出现：
Exception in thread "main" java.lang.IllegalArgumentException: adding a window to a container
at java.awt.Container.checkNotAWindow(Container.java:483)
at java.awt.Container.addImpl(Container.java:1084)
at java.awt.Container.add(Container.java:410)
at javaweb.LinkWin.<init>(JEditorPane1.java:39)
at javaweb.JEditorPane1.main(JEditorPane1.java:24)
，这儿无法显示图像界面，这儿有JFrame容器，怎么还需要窗口？？
------解决方案--------------------
editPane.add(this);
？？
这句话去掉。怎么在editPanel里add JFrame呢。
