Async BPEL Process Invocation...

Question

We have a business process, which when invoked from BPEL console works fine, however, when we invoke it from an web application of ours, it does gets initiated, but fails later.
We have Apache Axis deployed in the same OC4J server as the Oracle BPEL PM(10.1.2.0.2), which exposes few EJBs as SOAP Services.
The Business Process invokes couple of SOAP Services and then creates a Task and then waits for task completion and based on task action invokes two other SOAP services.
When we invoke it from the BPEL Console, everything works fine. It also works fine, if we invoke it first (after startup) from BPEL Console and then through our web application.
However, if we invoke it first through our web application, then it does initiates, but fails at the Task creation. If we try to hit the BPEL Console, we get this error
