Re: [rules-users] deleting records using rules

Hi, Thanks. Sorry for not being clear. I have the following: A = new A(); A1 = new A() B b1 = new B(A) B b2 = new B(A) B b3 = new B(A1) Each of the B above have a parameter "name" I am setting the name in one of my rules which works properly. I want to create an output list which: Checks that all B objects pointing to a single A object (eg. A1 or A in this case) have same name. If they don't I don't want to have them on my output list. I tried using forAll for the rule but that checks forALL B's in genral having same A object which is not what I want. Could you give me a starter / hint to create the rule. I even thought that I could maybe populate a list for each A object: When $a : A() b : B(a : $a , name == "x") Then Modify($a){ setAList(b) // adding all b's to a list contained in a }; But that does not help me achieve the second part as I cant traverse through a list inside rules. Any idea?? Please help.

That is easy for me to fix. Can I share the EntityManagerFactory, or should I create one for each session?

I will review that and let you know. On Tue, Jun 15, 2010 at 9:45 PM, Mauricio Salatino <salaboy@gmail.com<mailto:salaboy@gmail.com>> wrote: yes the problem is the environment.. I saw that problem in the past.. you need to create a separate environment object per each session.

Each thread in the test creates its own Drools session and executes its own workflow (which contains actions and work items that involve user interaction that is simulated by the unit test). This scenario tests the real-world case of our server handling sessions from multiple users. There should NOT be cross-talk between these sessions. Without persistence, everything works as expected. With persistence enabled, two sessions running in parallel are enough to fail 100% of the time. Each thread creates a session like this: session = JPAKnowledgeService.newStatefulKnowledgeSession(getKnowledgeBase(), null, getEnvironment()); The calls to getEnvironment() return the same value each time it is called called. Is this right? The environment is created like this: EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.drools.persistence.jpa"); environment = KnowledgeBaseFactory.newEnvironment(); environment.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf); Any idea where I messed up?

We have long-running processes (flows). They are long-running because we have work item nodes that involve the user of our application to do something. We are in the development cycle of our product and everything is going well. I am trying to configure persistence and running into some issues. I am to the point where our basic unit tests appear to be running fine with persistence enabled both in the container (tomcat6) and in our unit testing environment (ServletUnit). We have unit tests that run the same test in multiple threads in parallel (the idea is to try to expose thread safety issues), and these tests always fail. At the end of this message, I have pasted a few of the different stack traces I have seen. I expect that I have done something silly in the configuration, and I could use some help in finding it. I am not sure if the problem is my configuration of JPA, Hibernate, the DataSource, or if it is an interaction between what Drools is expecting and the details of my configuration.
