Re: [rules-users] Hibernate proxy objects equality tests failing in Drools 5

From: Guto <guto(a)guto.net&gt; Subject: Re: [rules-users] Hibernate proxy objects equality tests failing in Drools 5 To: "Rules Users List" <rules-users(a)lists.jboss.org&gt; Date: Monday, May 4, 2009, 2:42 PM Just now I notice one thing. The application that i am building is compleatly EJB centric. I have um EJB project that usually do all the database stuff, and another EJB project for the drools rules. Lets call them EJB-DATA and EJB-DROOLS. When the client calls for an specific data that must be threated thru the Drools rules it calls an Stateless method from EJB-DATA, inside the method, it gather the necessarie parameter information and them inside the EJB-DATA method it calls the EJB-DROOLS. (hoping not been confusing) (if you are using an fixed space font, here comes the sequence) Client --> EJB-DATA (gather information inside) --> EJB-DROOLS <-- return to Client data from EJB-DROOLS<-- return to EJB-DATA Now looking over my two projects, I notice that I make them apart so one could evolve with interfering the other. When I call EJB-DROOLS directly from an UNIT-TEST client with pojos parameters intantiated by the test, it pass. When I call EJB-DATA from an UNIT-TEST client (pojos created inside this), first i was getting an CORBA exception ´cause of a ClassNotFoundException for the hibernate PersistenceBag. That´s the way i figure out that my objects are bagged or proxied thru hibernate. I´ve tried to use the EntityManager.clear() (EJB3-JPA) to clean the pojos before send it and make them more like the ones from the first unit-test, but even so it´s not working. Then, possible solutions: 1) Make equality test works from objects that came from hibernate from jpa. 2) Kill the proxies and make them simple objects (not hibernate derivated). 3) don´t know, but i´m been realy in a deadline here. again thanks for anyone in advance ! -- Guto Maia Consultor de TI / Desenvolvedor CSM - SCJP- SCWCD - SCBCD - ZCE > In fact, i´m really using JPA with hibernate as an provider. > > Could you send me your hibernate config?
