No issues I got answer to this question . We were not initializing the persistence xml.Order of below statements is important and we had messed up there. 

<persistence-unit name="org.jbpm.persistence.jpa" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>jdbc/jbpmDS</jta-data-source>
