Resolution:
BusinessWorks provides WSDL/SOAP integration in a server and a client mode, which integrates directly into the Process Instance.  BusinessWorks provides three different components: SOAP Event Source, SOAP Send (Request) Activity, and SOAP Send/Receive (Request/Reply) Activity.  In BusinessWorks 2.0, we will only support document-centric calling convention and not a procedure-oriented communication. A future version of BusinessWorks will provide support for UDDI as well.
