  • The Client BPEL Process needs a valid partner link and an invoke activity.

  • The Service BPEL Process needs a receive activity.

  • As with all partner activities, the Web Services Description Language (WSDL) file defines the interaction. The WSDL file is as shown below.

<wsdl:portType name = "BPELProcess">
   <wsdl:operation name = "process">
      <wsdl:input message = "client:BPELProcessRequestMessage" />
      <wsdl:output message = "client:BPELProcessResponseMessage"/>
   </wsdl:operation>
