    No Class Loader error during deploy

    Arup Sarkar Newbie

      Hi:

      JBoss version 4.0.2
      Jdk 1.4.2
      MySql 5.0
      Myeclipse ide

      I have created a Hibernate capable project. I am using a service locator to identify the Hibernate Session Factory and Session using JNDI. I have created a hibernate.cfg.xml. I am also using hibernate doclet to generate jboss-service.xml, but I am getting the following error during deployment.

      "org.jboss.deployment.DeploymentException: No ClassLoaders found for: net.sf.hibernate.jmx.HibernateService; - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: net.sf.hibernate.jmx.HibernateService)"

      Any help would be highly appreciated.

      Regards
      Arup
