Class JPAProcessInstanceDbLog

java.lang.Object
  org.jbpm.process.audit.JPAProcessInstanceDbLog

public class JPAProcessInstanceDbLog
extends Object

This class is essentially a very simple implementation of a service that deals with ProcessInstanceLog entities.

Please see the public methods for the interface of this service.

Similar to the "ProcessInstanceDbLog", the idea here is that we have a entity manager factory (similar to a session factory) that we repeatedly use to generate an entity manager (which is a persistence context) for the specific service command.

While ProcessInstanceLog entities do not contain LOB's (which sometimes necessitate the use of tx's even in read situations, we use transactions here none-the-less, just to be safe. Obviously, if there is already a running transaction present, we don't do anything to it.

At the end of every command, we make sure to close the entity manager we've been using -- which also means that we detach any entities that might be associated with the entity manager/persistence context. After all, this is a service which means our philosophy here is to provide a real interface, and not a leaky one.
