Well now that I know I'm getting the "IllegalStateException: Transaction already
active" and no one seems to know anything about it, I looked further.
I am using 4 different persistence units:
* One for reading data from a source unrelated to the BPM component of my application
* One for the application data components associated with the BPM BPM component of my
application
* One for the BPM Process entities "org.jbpm.persistence.jpa"
* One for the LocalTaskServer entities "org.jbpm.task.persistence.jpa"
I was using the four spring JpaTransactionManager instances, one for each of the
corresponding EntityManagerFactories.
This was mostly working, but I was running into the above mentioned issues.
Well I saw the following comment in the JpaTransactionManager API documentation:
This transaction manager is appropriate for applications that use a
single JPA EntityManagerFactory for transactional data access. JTA (usually through
http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springfr...
JtaTransactionManager) is necessary for accessing multiple transactional resources within
the same transaction. Note that you need to configure your JPA provider accordingly in
order to make it participate in JTA transactions.
So, I reconfigured the
persistence units and application context to use the JtaTransactionManager
(
http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springfr...),
and now when I do something like claimTask(), I get: an "IllegalStateException: A JTA
EntityManager cannot use getTransaction()"
Can anyone help me now? Why is org.jbpm.task.service.TaskServiceSession.taskOperation
calling getTransaction directly?
