HTTP Invoker and Session Tracking

Need expert advice on session tracking with HTTP invoker. I am working on a client-server app running on Windows. The server is OSGi + Spring Blueprint and client is Swing + Eclipse plugin + Spring. Spring HTTP invoker is used for remoting. Session tracking is needed to meet the requirements, however, Spring HTTP invoker doesn't seem to support session tracking out of the box.

One solution I can think of is to have session ID in every remote method call. Is it a reasonable solution? or should I try to implement stateful http invoker http://forum.springsource.org/showth...implementation.

Thanks in advance.
