Hello Cliff,
Thanks for the insight you've given in your email.

But isn't 109 based on JAX-RPC anyways? I would think that something 109 can't do, JAX-RPC could not do either. Have I misunderstood the whole thing? I thought that 109 simply leveraged JAX-RPC and built on top of it.
Thanks,
Mete

>> The web service that we want to build is for a CRM product. Although we want to take this opportunity to completely revamp our back-end CRM application and port it into a J2EE environment and not have any baggage from the old system. We are already in the process of building a JCA Connector for the old back-end system for use in Java-based portal servers. But we want the next generation of our CRM product to interface the outside world via Web services. Therefore I was investigating possible architecture options for a completely new CRM application with a web service front.
