WSRP - Pass Custom Data between Consumer and Producer

Question

Hello All,
I am having a couple of queries with respect to Custom Data Transfer. Consider I have a Map of values which I need to transfer between both Consumer and Producer.
For eg: the map that Consumer sends would contain "firstName", "lastName", etc... On the other hand Producer needs to do some business function based on the data and add more values to the map like "rewardPoint" etc....
On Consumer Side:
I have choice to use Backing File or IGetMarkupInterceptor to implement the preInvoke to pass the data using SimpleStateHolder.
Question: I am not able to send a simple Serializable POJO Object... I can only send primitive / default java objects like Strings, Maps of String etc. Is my understanding correct?
On Producer side:
I am able to receive the Custom Data from request. No problems. Now how to send more data from Producer to consumer. I need to add the "rewardPoints" into the map and send back.
My understanding is that if the Producer puts any values into StateHolder objects, Consumer will receive it in IGetMarkupResponseContext object in the Interceptor's postInvoke method.
Question: How do I get a handle to the IGetMarkupResponseContext object @ Producer end???
Question: Do I need to write some interceptors on Producer end? If so which file I need to use?
Any help / pointers would be greatly appreciated.
Thanks,
Paz

Hi All,
I tried to set the data in the producer using the following command
SimpleStateHolder stateSimpleOuterReq = (SimpleStateHolder)request.getAttribute(MarkupRequestState.KEY);;
          if (stateSimpleOuterReq == null) {
               SimpleStateHolder state = new SimpleStateHolder();
               state.addParameter("name", "data1");
               request.setAttribute(MarkupResponseState.KEY, state);
I am not able to retrieve the same in consumer.
The above is a WSRP struts request.
I also tried setting the data by unwrapping the request in producer and still value is null in consumer :-(
          HttpServletRequest requestq = (HttpServletRequest)((HttpServletRequestWrapper) request).getRequest();
          SimpleStateHolder stateSimpleReq1 = (SimpleStateHolder)requestq.getAttribute(MarkupRequestState.KEY);
               if (stateSimpleReq1 == null) {
                    SimpleStateHolder state = new SimpleStateHolder();
state.addParameter("name", "data1");
                    requestq.setAttribute(MarkupRequestState.KEY, state);
Please help me in resolving the issue. Correct me if i am doing anything wrong.
Thanks
