Struts 2.0.5: Could not execute action

Mon, 19 Feb 2007 02:58:02 -0800 

Hello,
I have managed to create a web application which uses Struts 2.0.5 build. When deploying the application into a Tomcat 5.5.20 server it starts without errors. Problem occurs when trying to call an action. Following is what I get. Any idea what might cause this? 

Regards,

- Tapio
