    MBean's JNDI attribute times out at JBoss startup but works

    toto titi Newbie

      Hello,

      I'm facing a curious problem, trying to expose Hibernate's statistics through JMX. I updated jboss-service.xml to add the following:

      <mbean code="org.hibernate.jmx.StatisticsService"
       name="jboss.monitoring:service=StatisticsService,name=xxxStatisticsService">
      
       <attribute name="StatisticsEnabled">true</attribute>
       <attribute name="SessionFactoryJNDIName">persistence.units:ear=xxx.ear,jar=xxx.jar,unitName=xxx_pu</attribute>
      
      </mbean>
      


      When JBoss AS starts, I receive the following error:

      16:36:46,532 INFO [Server] Core system initialized
      16:36:53,188 ERROR [StatisticsService] Error while accessing session factory with JNDI name persistence.units:ear=xxx.ear,jar=xxx.jar,unitName=xxx_pu

      Please note that this occur every time for this JNDI attribute, but not if I set a simple value (i.e. a plain string with no special char).

      However, once the server is started, I can access my MBean through the JMX console, set the SessionFactoryJNDIName attribute with the same value, and then see updated Hibernate statistics as I first expected. I double-checked this value, which seems to be the real JNDI name for my Hibernate SessionFactory.

      I guess this is a JBoss AS issue, but how can I solve this, or work around this?

          Well, my statement about a "simple value" working OK was just wrong.

          The above error message appears with anything I take from the Global JNDI Namespace (as displayed by JNDIView in the JMX Console). A value from any other namespace gives the following error (here with a random ConnectionFactory):

          17:12:11,574 ERROR [StatisticsService] No session factory with JNDI name java:/ConnectionFactory
          javax.naming.NameNotFoundException: ConnectionFactory not bound


          Is this a hint about what is happening?
