tomcat出现错误，请各位前辈帮忙看下

小白棉花糖

浏览器输入http://ip:8080/cwoa2011/setup后出现500错误，怎么破？

如下：

HTTP Status 500 - Filter execution threw an exception

--------------------------------------------------------------------------------

type Exception report

message Filter execution threw an exception

description The server encountered an internal error that prevented it from fulfilling this request.

exception
javax.servlet.ServletException: Filter execution threw an exception



root cause
java.lang.NoClassDefFoundError: Could not initialize class com.redmoon.oa.pvg.Privilege
        com.redmoon.oa.DownloadFilter.doFilter(DownloadFilter.java:21)



note The full stack trace of the root cause is available in the Apache Tomcat/6.0.43 logs.

--------------------------------------------------------------------------------

Apache Tomcat/6.0.43

谢谢各位！

感觉像是tomcat根本没启动成功，你可以看看它的启动日志报错了没有

java.lang.NoClassDefFoundError，没有类包，看看类包是否正确，根据配置文件查看类包位置
或者直接咨询开发
