sure. Attached process file, JUnit for WorflowService and service implementation.
m working on a sample flow to explore jBPM. Error occurs when junit test for I WrokfloeService.signalExecutionByBusinessKey() is executed. I have tested the service method with HSQL and Oracle Database 10g Express Edition Release 10.2.0.1.0 and result is same :-(
I will be spending some time to jBPM sources files where a new ProcessInstance is created and hope that I will get some clue!
Thanks
