Hi All

error

1. what is the issue here?

2. Why does the jbpm-test-6.0.1-20140120.jar need to be referenced for the
solution to work?

3. Because of question 2 giving me problems I googled some and found this Issue
running sample project - jBPM 6.0.1 Final, this comment in particular: Re:
Issue running sample project - jBPM 6.0.1 Final

    As per that post  Re: Re: Issue running sample project - jBPM 6.0.1
Final, created the persistence.xml (attached) but the test code still didnt
work.

    I copied the code and tried to run the code as follows in a main() with
an EntityManager as recommended in the post (as attached Run.java)


    Then i get this

     Caused by: org.hibernate.service.jndi.JndiException: Unable to lookup
JNDI name [jdbc/jbpm-ds]


    Most likely the persistence.xml in the test jar mentioned in (2), so i
remove it from includes and rerun


    Exception on Run.java line 67

    Exception in thread "main" javax.persistence.PersistenceException: No
Persistence provider for EntityManager named org.jbpm.persistence.jpa


    Then i try to swap my boolean old to false to run the code with an
EntityManager defined (Run.java line 40):


    Exception raised on EntityManager


Exception in thread "main" javax.persistence.PersistenceException:

So how do i get it to point to the data source defined in the demo (
<jta-data-source>java:jboss/datasources/jbpmDS</jta-data-source>)?


Thanks in advance,
