Struts App dispatcher error on Tomcat 5.5.23

[Venkat Tanga]

Hi,           I just migrated my application from Tomcat 5.0.18 to 5.5.23.           On server startup Application loading is happening normally, but once I logged into the application and try to access any links, there I am facing the problem.           The Application is being developed on :  Jdk 1.4 , Struts 1.1, Cocoon 2.0.4.           Plz find the below mentioned Error stack trace. Can any one plz suggest  me on this. Does any of my old libraries methods are leading to this problem in the new Tomcat 5.5.23 environment in application re-direction?
