Java EE (Java Enterprise Edition) General Discussion

I have been having this problem from quite some time:
What do i have to install to get a standard Tomcat to run my Webservice
using JWSDP (JAX-RPC in principle).

Problem: I want to deploy a webservice on an ISP Host. Every ISP supplies me with a version of Tomcat but does not let me install JWDSP and deploy the Tomcat that came with JWSDP. What packages do I need in my WEB-INF\classes? They only let me upload a war file and that's it.

I tried: Writing a small webservice and deployed it on the tomcat that came with JWSDP - it worked. The same webservice did not install on a standalone Tomcat whatsoever. I think, better yet, i hope, i have set the classpath of the new installed packages of JWDSP right so the Tomcat standalone ver. should know about them. I did not work.

My solution: Haveing a Tomcat, I used APACHEs version of SOAP. I installed that in my WEB-INF dir and it worked fine.
Problem with my solution: I Don't LIKE IT! I want to use JAX-RPC

Reformulation of the problem: What packages do i need to put where so my Webservice can run on any standalone Tomcat version weather or not that ISP has JWSDP installed or not.

Thx
