BindingFault - GenericError - null

Question

Hello everyone,
I urgently need a solution to a problem I'm facing with an asynchronous BPEL process on Oracle BPEL PM 10.1.2.0.2 that I invoke from a java proxy client.
To try to reproduce the problem, I created a very simple async BPEL process that accepts a single string and returns the same string. I tested the process in BPEL Console and everything works fine. I created a java proxy client and a callback web service.
When I invoke the process from java, the callback always fails with the following message:
<bindingFault>
<part name="code" >
<code>GenericError</code>
</part>
<part name="summary" >
<summary>null</summary>
</part>
</bindingFault>
I added an invoke step to manually invoke the callback web service just before the callback step, and that invocation executes successfully. That way I know nothing wrong with the callback webservice.
I captured the soap packet as follows:
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns0="http://schemas.xmlsoap.org/ws/2003/03/addressing" xmlns:ns1="http://xmlns.oracle.com/AsyncBPELProcess">

               <ns1:input>TEST</ns1:input>
          </ns1:AsyncBPELProcessProcessRequest>
     </env:Body>
</env:Envelope>
I even tried to create the partnerlink dynamically using bpelx:headerVariables, but later found out that it is not supported in Oracle BPEL 10.1.2.0.2.
Has anyone encountered this problem? My deadline is approaching and I need help soon!
Thanks,
Karwan
