Hi Kiram, We are currently working, through the spring integration, on adding support for using processes without JTA. The only pending feature is the automatic rollback handling that JTA provides, that means that you *MUST* reload the session instance after a rollback. Here you have an example app: http://www.plugtree.com/downloads/DroolsFlowSpring.tgz -- Baunax On Wednesday 19,May,2010 09:22 AM, KiranP wrote:

@KiranP, Can't paste the whole thing: client work. As to your error, at which point do you get it? When the framework tries to create a SessionInfo record? Or you process goes to the wait state, and the framework is unable to commit ( JPA Persistence )? Or your DAO within a work item handler can't commit.... etc.. /Anatoly -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Drools-5-1-Persistenc...
