    weird jar dependency loading problems

    Hany Bee Newbie

      When I configure the Hibernate mbean service, I get a weird problem about missing dependency class.

      I added the following to $server/conf/jboss-service.xml:


      jboss.jca:service=RARDeployer
      jboss.jca:name=DefaultDS, service=LocalTxCM

      test/web/project/beans/Event.hbm.xml, test/web/project/beans/User.hbm.xml

      java:/hibernate/HibernateFactory
      java:PostgresDS
      net.sf.hibernate.dialect.PostgreSQLDialect
      net.sf.hibernate.transaction.JTATransactionFactory
      net.sf.hibernate.transaction.JBossTransactionManagerLookup
      UserTransaction


      When I start up JBoss, it would complain about missing class file:

      .....

      I can only solve this problem by copying the files commons-logging.jar
      and log4j.jar to $server/lib. This does not make sense, these two packages are used by almost all components in JBoss, and it didn't complain about it, until I configure the Hibernate mbean.

      What's wrong with this?
