Both are true. 5.4.x supports local transactions +using a spring transaction manager+, but does not support pure local transactions with a normal transaction manager. -- Reply to this message by going to Community [https://community.jboss.org/message/828773#828773] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1containerType=14container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Marco Rietveld [http://community.jboss.org/people/marco.rietveld] created the discussion Re: Persistence and Transaction Management To view the discussion, visit: http://community.jboss.org/message/617007#617007 -- Hi Marco, Thanks very much for posting all of this! Could you maybe clarify +why+ you want to use application-managed persistence with jBPM? You probably know this, but for clarification: RESOURCE_LOCAL means that you want the entityManager (e.g. the persistence layer) to be managed by the application. Application-managed persistence is most often used by servlets, EJB's, and locally running java applications because these are in essence small programs that don't need the extra overhead that container-managed persistence brings with it. These programs usually open a persistence context/connection, get the stuff they need, commit the stuff they changed, and clean it all up: there is no usually no need for fine-grained control transactions. In my opinion, jBPM does need more fine grained control over transactions. It needs this because +when+ objects/data (and which objects/data) are persisted is a more complicated question. JTA gives you this control. Furthermore, I think there might be cases when you want to commit some objects while leaving other objects in the persistence context (logging objects vs. process context information). In short, 1. jBPM needs to be sure that the persistence context is always available, which would be more work for jBPM with application-managed/ (container-managed persistence just works.. :-)) and 2. jBPM needs fine-grained control over transactions, which is easier with JTA. Does that make any sense? If I'm missing something, please point it out! -- Reply to this message by going to Community [http://community.jboss.org/message/617007#617007] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1containerType=14container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

It seems that the RESOURCE_LOCAL transaction-type is not supported. Indeed if I simply delete transaction-type=JTA from the persistence.xml, this NPE is thrown. Caused by: java.lang.NullPointerException at org.drools.persistence.SingleSessionCommandService.init(SingleSessionCommandService.java:138) ... 36 more The cause is that the SingleSessionCommandService try to set a sessionId that has not been generated in that line: ((InternalKnowledgeRuntime) ksession).setId( this.sessionInfo.getId() ); I don't know if that is an issue (JBPM is supposed to support the RESOURCE_LOCAL transaction type?). Anyway, if the RESOURCE_LOCAL is not supported, the API should detect this situation and communicate that in a more nicer way... Could we add an issue to Jira about that? -- Reply to this message by going to Community [http://community.jboss.org/message/614099#614099] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1containerType=14container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

The documentation says: Whenever you do not provide transaction boundaries inside your application, the engine will automatically execute each method invocation on the engine in a separate transaction So, if I do not specify the TransactionManager (and do not start a transaction programmatically) I expect that a transaction manager is used transparently by JBPM. Indeed, it seems that org.drools.persistence.jta.JtaTransactionManager is used by default (throwing a NPE!). But that is quite confusing, since the persistence-unit's transaction-type is RESOURCE_LOCAL. Any hint about that? -- Reply to this message by going to Community [http://community.jboss.org/message/613404#613404] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1containerType=14container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
