Hi,
When I try to run a sample test case using drools-persistence.jar it works successfully.
But when I try to include the persistence in my OFBiz application, I am getting null pointer exception in class JPAWorkItemManager.java.

java.lang.NullPointerException  
 at org.drools.persistence.processinstance.JPAWorkItemManager.completeWorkItem(JPAWorkItemManager.java:85).

Null Pointer is because of getting EntityManager object as NULL. In the below line of JPAWorkItemManager.java
  EntityManager em = (EntityManager) this.workingMemory.getEnvironment().get( EnvironmentName.ENTITY_MANAGER );
the em is null.
Because of this I am getting Null Pointer exception when it try to run the code
 if (workItemInfo == null) {
                workItemInfo = em.find(WorkItemInfo.class, id);
        }
 
Can you tell me why I getting NPE when I try to run the jar file in my application.
While the code run successfully when I try to run sample test case for that.
Please help me to get through the situation.


Thanks & Regards
