  I wrote my own SOAPServlet to allow people to write SOAP-enabled webapps. I use the same methodology for EbxmlServlets. To write a webapp for a given protocol, you simply subclass the appropriate servlet just as you would with HttpServlet. I also subclass ServletRequest and Session to allow access to high-level helpers and interfaces for SOAP and ebXML. These helpers make up the framework that allows you to create and access things like Collaboration, Conversation, and BusinessProcess objects.

  The client-side code is a lower-level set of classes that constrains the creation and communication of messages. The same framework helpers and interfaces are used on the client side to deliver a consistent API feel.
