I'm trying to write a BPEL process which receives callbacks from a third-party service. I can successfully invoke synchronous calls to/from that service. It has published a separate WSDL for its callbacks. I have (after some problems) managed to get jBPM to use this WSDL and it can successfully wait for and accept the incoming requests. However, if I try to inspect any of the incoming message data, no matter what I try, I'm getting an uninitialised variable error.

The message definition in the WSDL is element style; it looks like:
< message name="ImportCompleteEventIn" >
< part name="in" element="store-types:ImportCompleteEvent"/ >
< /message >

The variable definition looks like this:
< bpws:variable messageType="scwsdl:ImportCompleteEventIn" name="storeCallbackImportCompleteVar" />

The receive:
< bpws:receive partnerLink="StoreCallbackPL" operation="ImportCompleteEvent" variable="storeCallbackImportCompleteVar" />

Has anyone seen this before? Any suggestions? I can't publish the entire 3rd-party WSDL here.

I have also tried using both a < receive > and a < pick >< onMessage > structure, and they both exhibit the same problems.


However, this might be caused by some other jax-rpc problem. When I deploy this BPEL process, I get these messages appearing on the JBoss stdout:
09:48:27,612 WARN [builder.jaxrpc.JAXRPCMetaDataBuilder] Cannot obtain java type mapping for: {http://www.w3.org/2001/XMLSchema}string

...

I also get similar messages for some of the elements defined in my 3rd-party schema.

Many thanks for any help you can give.
