Hi,
I'm trying to create a BPEL for asynchronous web service call. A snippet of it
is shown below:
<!-Receive request from client -->
<receive createInstance="yes" operation="initiate "
partnerLink="ApprovalProcessClient" portType="ns1:approvalProcessPT"
variable="approvalProcessRequestMessage"/>
<!-Asynchronous Web Service Invoke -->
<invoke inputVariable="asyncApprovalRequest" operation="submitForApproval"
partnerLink="AsyncApprovalPartner" portType="ns2:asyncApprovalServicePT">
<correlations>
<correlation initiate="yes" pattern="request" set="CS1"/>
</correlations>
</invoke>
<!-Receive Response from Asynchronous Web Service invoked above -- >
<receive operation="onResult" partnerLink=" AsyncApprovalPartner "
portType="ns1:asyncApprovalCallbackPT" variable="asyncApprovalResponse">
<correlations>
<correlation initiate="no" set="CS1"/>
</correlations>
</receive>
The first receive in the above BPEL snippet is called by a client and therefore
I have declared it as a 'service' in componentType file.
The invoke is for invoking an asynchronous web service operation. The portType
of that I have declared as 'reference' in the componentType file.
The second receive in the above BPEL snippet acts as a callback to receive
response from an asynchronous web service. Where and How do I specify that this
is a callback? Is there way of specifying callbacks in componentType file.?
Thanks & Regards
Ashwini Kumar Jeksani
