User development, A new message was posted in the thread "org.hibernate.MappingException: Named query not known: findP": http://community.jboss.org/message/521402#521402 Author : Ronald van Kuijk Profile : http://community.jboss.org/people/kukeltje Message: -------------------------------------------------------------- Delayed response, but I'll give it anyway in case others come across it.   RepositoryService is to be used in normal operations. It's *part of the public api* (org.jbpm.api). DBSession is to be used when low level stuff is done (the repository service internally uses commands which in turn use DBSession) and *not part of the public api* (org.jboss.pvm.internal). You can use it, but *no guarantees on stability* etc... You can retrieve the current hibernate session from it and do anything in the database you want.   So when implementing new commands and they have to do things that are not available trough services, use the DBSession. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521402#521402
