BPEL Pick and Wait activity for Synchronous Process

Question

Hi everyone,
Is it possible to use the pick and wait activity in bpel for recieving the synchronous webservices response .I need to invoke a synchronous webservice and want to use the pick activity onmessage branch to recieve the response of the synchronous webservice. I have tried the pick activity to recieve the response of asynchronous bpel process it is working fine.Now if i want to use the pick activity to recieve synchronous webservice response is it possible ?
If someone can help me in this regard it would be great.
Thanks in Advance.

Answer 1

that's the thing , you can't
You must create another bpel (sincr ) in front of your asincr(bpel)
the sincr bpel will have a pick activity on the onResult(or onError) message from the asinc bpel. You pass the payload from OnResult to output and voila.
The asincr bpel will have at least 3 operations .
1. operation -
2.onMessage
3.OnResult
(4.OnError )
Be carefull how you put the roles and port types in the wsdl file. The callback must be first.
<portType name="xCallback">
<operation name="OnResult">
<input message="ns1:xResponseMessage"/>
</operation>
<operation name="OnError">
<input message="ns1:xFaultMessage"/>
</operation>
</portType>
<portType name="x">
<operation name="process">
<input message="ns1:xRequestMessage"/>
</operation>
<operation name="OnMessage">
<input message="ns1:xResponseMessage"/>
</operation>
</portType>
<plnk:partnerLinkType name="x">
<plnk:role name="xProvider">
<plnk:portType name="client:xCallback"/>
</plnk:role>
<plnk:role name="xRequester">
<plnk:portType name="client:x"/>
</plnk:role>
</plnk:partnerLinkType>
