Messaging in contrast to RPC

Hi all,

I have implemented various services using SOAP RPC, but the services are possibly better suited to messaging. Essentially an initial request for a web service I provide should return a stream of message responses overtime. It is a very asynchronous interaction. Is this really feasible using Apache SOAP? I am particularly unsure whether it is possible to send a client message responses overtime after that client has registered an interest.

Thanks in advance,

Darren Marvin

There is certainly no obstacle to what you propose as long 
as you don't insist on using HTTP for transport. 

I did some experiments with JavaMail, Java Message Service 
and JavaSpaces messaging for my forthcoming book on Soap
programming with Java. SOAP messages fit in just fine.
