NPE when using JBPM in Seam without a DbPersistenceServiceFactory confirgured
-----------------------------------------------------------------------------
Key: JBSEAM-2312
URL: http://jira.jboss.com/jira/browse/JBSEAM-2312
Project: JBoss Seam
Issue Type: Bug
Components: BPM
Affects Versions: 2.0.0.GA
Reporter: David Heggie
Priority: Minor
I have noticed that when using JBPM with Seam, a DbPersistenceServiceFactory must be
configured in the jbpm.cfg.xml, otherwise a NullPointerException occurs. I know that you
can run JBPM by it self without persisence configured and it works just fine.
Is there a specific reason why JBPM must be configured with a persistence service in Seam.
If not, there is a simple null check that can be done in the
org.jboss.seam.bpm.Jbpm.initJbpmConfiguration() method to fix my problems.
Also the Jbpm class has a few dependancies on Hibernate that would be nice to remove as it
is annoying to include the whole jar just for 2-3 classes.
