mputz, I tried it just now - but unsuccessfully. I use Firebird as JBPM DB, and as far as I can see - the JobExecutor holds opened transaction from its start to infinite... The only one solution I can find is https://jira.jboss.org/jira/browse/JBSEAM-3837 - because https://jira.jboss.org/jira/browse/JBPM-1166 still not fixed. But, sporadically it causes deadlocks in Firebird and/or conflicts in Entity Manager, so I decided to make separate webapplication for Job Executor instead of two context (Seam'ed and Seam'less) in one app. Of course it's stupid way but simple, anyway it works for me :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4196568#...
