Re: [rules-users] Drools Human Task Service Persistence
wait a minute, is it like no one ever tried persisting human task in oracle before? so far the support is only for H2 in memory db? i wonder how this made into production system then? honestly, its not criticism, just wanted to know how others are doing without persistence of task, of course DB is not only oracle, they might have used other DB as well. But it doesn't ring me a bell how custom status be implemented and how the named queries in org.drools.task be executed, lacking of proper docs and examples ..creating lot of chaos :-( So, you can't do persistence with oracle unless u have to override, if not oracle, what is the best bet DB (please don't say H2 :-) ) -drooRam -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Drools-Human-Task-Service-Persistence-tp1868778p1925280.html Sent from the Drools - User mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] Is annotation possible in Rule flow constraint editor
Hi I just want to know whether annotation and spring ioc is possible with rule flow constraint editor. For example, in any constraint editor, drools have two supporting types of coding, mvel & java.

[rules-users] Object not seen in working memory i.e not evaluated by rules
Hi I tried to do a simple test case using spring drools. Following is the test class, it inserts customer object into the workflow.rf and fire the rules 1. nameShouldBeEntered & 2. emailShouldBeValid I have also attached drl, rf and applicationContext.xml files in this mail. nameShouldBeEntered Rule is fired since its just evaluating to true by default. But emailShouldBeValid rule has not been evaluated if i debug through test case since customer object has not seen in working memory I believe. I added customer variable in RF, also inserted using kession.insert, also passing using paramenter's map in startProcess()...nothing helps... i think its due to some class loader issue or i might be doing some thing wrong in the code...but it looks pretty straight forward and i analyzed the code thoroughly ..could anyone tell me what i am missing in this code?

[rules-users] ksession.dispose() and DroolsSpringJpaManager.dispose()
I have question on kession.dispose(), what is the best place to call this method? I have a code where in i call ksession.startProcess("someprocess", mapParam); ksession.fireAllRules(); finally{ ksession.dispose(); } If i invoke the kession.dispose() like the above, I always ended up in "No value bound to the key" - Transaction exception. My understanding is that all the calls to drools should be enclosed in a transactional unit. I have done that so. My observation is that DroolsSpringJpaManager.dispose() method is being invoked due to my call to ksession.dispose() after the transaction has begun from my app code and right before the transaction.aftercompletioncommit() call. I can see a line of code in DroolsJpaManager.dispose() method, TransactionSynchronizationManager.unbindResource(this.emf) // entityManagerFactory reference borrowed from application code. My question is that why the above line of code is necessary in dispose() method since this.emf is the reference obtained from Application code jpa manager, since this method unbinded this resource, transaction initiated from the application code is also trying to unbind the same resource once everything is completed results to "No value found for this key exception". When i comment out ksession.dispose() call from my app code, it works fine. At this point, i am not sure when to invoke ksession.dispose() call and why the TransactionSynchronizationManager.unbindResource(this.emf) being made in DroolsSpringJpaManager.dispose() on a reference obtained from JpaTransactionManager ? -drooRam -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/ksession-dispose-and-DroolsSpringJpaManager-dispose-tp1531549p1531549.html Sent from the Drools - User mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
