Hi, I'm hoping someone can point me in the right direction. I have a number of problems with Jbpm but they are probably all related to the fact that I need to learn a lot more about it.

But I have come to a stop when it comes to implementing a workflow with a fork in it. I'm using JBPM 4.0. When I attempt to run my test class I get an SQL exception.

This is the code I am using to test my workflow.

 deploymentId = repositoryService.createDeployment()
 .addResourceFromClasspath("process.jpdl.xml").deploy();

 ProcessInstance processInstance = executionService.startProcessInstanceByKey("process");
 String processInstanceId = processInstance.getId();

My work flow looks something like this. I've simplified it but I'm pretty sure I'm doing something pretty basic wrong here.

<process name="process" xmlns="http://jbpm.org/4.0/jpdl">
 <start>
 <transition to="first transition" name=""/>
 </start>

 <java class="org.companyname.class.AClass" method="execute" name="first transition">
 <transition name="" to="fork"/>
 </java>

 <fork name="fork">
 <transition name="" to="start a process" />
 <transition name="" to="start second process" />
 </fork>

 <java class="org.companyname.class.BClass" method="execute" name="start a process">
 <transition name="" to="join"/
 </java>

 <java class="org.companyname.class.BClass" method="execute" name="start second process">
 <transition name="" to="join"/
 </java>

 <join name="join">
 <transition name="" to="process joined"/>
 </join>

 <java class="org.companyname.class.CClass" method="execute" name="process joined">
 <transition name="" to="end"/
 </java>

 <end name="end"/>
 </process>

The exception I'm getting is this

16:55:02,332 WRN | [JDBCExceptionReporter] SQL Error: 1062, SQLState: 23000
16:55:02,332 SEV | [JDBCExceptionReporter] Duplicate entry 'fraud.70.' for key 2

If anyone can provide me with any sort of guidance then it would much appreciated. As you can probably tell I'm on a steep learning curve with Jboss and JBPM.

Regards
M
