Deployment of JSP in webMethods provided tomcat

I have deployed JSP – Servlet application in apache tomcat version 4.0. Now I need to move this code to webMethods and use its inbuilt tomcat to deploy the application. I have placed the jsp files under the web folder and servlet files under web-INF and utility classes under web-inf/classes folder. I did the same thing for apache tomcat. Under normal apache tomcat I do not face any problem. But when I ported the code into webMethods and placed in directory structured listed above, JSP is unable to locate my servlet class?? Do I need to do something extra from my side so that JSP file can access the servlet ?? Has somebody come across this problem?? I would really appreciate any help or direction.

Thanks

Refer to ISJSPGuide.pdf. It explains everything about running JSPs in Integration server.
