JBPM integration

Hi all,
i just would like to share with you, that I achived a simple integration of JBPM Workflow Engine with Neo4J. I created a work item handler capable to execute a cypher call from JBPM and returning the results in JBPM as Workflow Data. If anyone is interested in such a handler I would be glad to share the code / eclipse project so far.
