    Brms persistance.xml loading in MDB

    Ale Ale Newbie

      Hi,

           I am trying to trigger jbpm events from a jms queue.

           I use EAP 6.1.0 with BRMS 5.3.1. deployable.

       

           I created an "org.drools" module including all brms libs.

           And referenced it in my custom Classes.

       

           Custom ejb references myBPMUtils

           myBPMUtils uses the BRMSlibs

       

          Here is the code invoking JTA

       

      EntityManagerFactory emf = Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" );
      
      

       

               

           Here is my custom libs module xml.

       

      <module xmlns="urn:jboss:module:1.1" name="it.utils">
          <resources>
              <resource-root path="BPMUtils.jar"/>
              <!-- Insert resources here -->
          </resources>
      
      
          <dependencies>
              <module name="org.drools"/>
              <module name="org.jbpm.persistence.jpa"/>
          </dependencies>
      </module>
      

       

      Module is made global in standalone .xml and correctly used by my EJB.

       

      I put following persistence.xml in my META-INF FOLDER

       

      <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
      <persistence version="1.0"
        xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd

          <class>org.jbpm.process.audit.ProcessInstanceLog</class>
          <class>org.jbpm.process.audit.NodeInstanceLog</class>
          <class>org.jbpm.process.audit.VariableInstanceLog</class>
      
      
          <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
            <property name="hibernate.max_fetch_depth" value="3" />
            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.show_sql" value="false" />
            <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transact" />
      
      
            <!-- BZ 841786: AS7/EAP 6/Hib 4 uses new (sequence) generators which seem to cause proble -->
            <property name="hibernate.id.new_generator_mappings" value="false" />
          </properties>
        </persistence-unit>
      </persistence>
      

       

      And I get the following error when I try to start my EJB.
