Sun 早期有关于此问题的错误报告，使用 JDK 1.4

您主要运行 JDK 1.6，但请查看 bug report .

简短摘要(收集from this forum):

The Java plug-in of your browser tries to get some .class file from the current location (your server) and fails because your server returns some custom 404 page. Let's try to check the Java console to see what really is requested. Please, run the Java console, set the trace level to 5 (highest level).

启用Java console on Windows for IE browser并查看它是否提供有关哪个 URL 出现 404 或其他错误的详细信息。
