I think this might be a good starting point for you:
http://www.caucho.com/hessian/ but please be careful when running sub-processes and heavily multi-threaded servlets (make sure they work properly before uploading them) remember your using a shared JVM, I don't think the Admin at lunarpages will appreciate you crashing it - you might consider enquiring about a Private JVM.
