    Hibernate - Help getting started with Hibernate

    Michael Not relevant Newbie

      Hi,

      I am having trouble deploying an EAR that contains a HAR. I wonder whether anyone can help me get started with hibernate/jboss..?

      My EAR looks like this:

      myapp.ear
      -META-INF/application.xml
      -META-INF/jboss-app.xml
      -jboss.har
      --hibernate-service.xml
      --mdbtest/ejb/Document.class
      --mdbtest/ejb/Document.hbm.xml
      -testClient.jar
      -testEJB.jar

      The console log shows the following null pointer exception:

      10:56:11,463 INFO [EARDeployer] Init J2EE application: file:/usr/local/jboss-4.0.0/server/default/deploy/myapp.ear

      hibernate-service.xml looks like this:

      <?xml version="1.0" encoding="UTF-8"?>
      
      <server>
       <mbean code="org.jboss.hibernate.jmx.Hibernate" name="jboss.har:service=Hibernate">

      jboss-app.xml looks like this:

       <module>
       <har>jboss.har</har>
       </module>
      </jboss-app>
      


      If anybody can help me set this up correctly, I would be HUGELY grateful :-)
