[jboss-user] [jBPM] - one of the ways to integrate JPA/Spring with jBPM

O S [http://community.jboss.org/people/gelos] created the discussion "one of the ways to integrate JPA/Spring with jBPM" To view the discussion, visit: http://community.jboss.org/message/539262#539262 -------------------------------------------------------------- I tried to research this before on this forum and I don't think that there is a consensus on how to make jBPM to work seamlessly with JPA/Spring We implemented an approach that works for us and I figured I will describe it here and see if there is any feedback from the community thanks, gelos ---------------------------------------------------------------------------------- - problem overview   - when JPA/Spring is used the desire is to make jBPM to join JPA transactions seamlessly   - the issue boils down to Hibernate sessions - how to inject sessions managed by Spring to jBPM   - Spring manages EntityManagerFactory and EntityManager objects and a common approach (which we use) is to use @PersistenceContext() annotation in DAO objects and have Spring inject EntityManager instances (which are wrappers around Hibernate sessions) into DAOs   - so we need to get a hold of EntityManager, get the underlying Hibernate session and provide it to jBPM when it asks for it - solution overview   - implement custom jBPM wire object for HibernateSession   - in the object descriptor make a call to a bridge object that uses @PersistenceContext() and is managed by Spring and get Hibernate session from it every time jBPM needs it see the attached files for details. code has comments in it -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/539262#539262] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
