Hi there,

at the moment I am evaluating the capabilities of jBPM in combination with BPMN2.0 processes. Therefore I created a process with the academic version of Signavio and exported it as BPMN-DI (jBPM_Testprozess.bpmn.xml). Then I deleted the DI stuff because it seems not yet to be supported in jBPM. After that I adopted the Service Tasks like described in the  http://docs.jboss.com/jbpm/v4/devguide/html_single/#bpmn2 developers guide bpmn2.0 section. Then I wrote a Java class with a simple echo-method to test around a bit (DbOperations.java). After that I created a UnitTest (ProcessTest.java). When I run my test I get the following exception:

org.jbpm.api.JbpmException:

The three important files are attached to this Thread. I use jBPM4.3 under Ubuntu 9.10 on Java(TM) SE Runtime Environment (build 1.6.0_20-b02).

I don't know what the exception tells me, can someone help me with that?
