struts app cannot run under Tomcat5

[Kero Gu]

I have an application running well under Tomcat4.
But it doesn't work under Tomcat5.
When I call my .do action, system tells me that:
---------------------------------------------------------------------------

Here is part of my web.xml content.
If I subsitute ActionServlet with my testing HelloServlet, Tomcat5 can execute HelloServlet.do and echos "Hello World" on the controll panel.
But ActionServlet cannot work.
