    Deployment of a J2EE1.3 application fails on JBoss4.2.2

      Salut,

      i have successfully set up a JEE1.4 environment for to test
      and run my applications using EJB3. Fine!

      Some days ago i started a migration project, where an
      old JEE Application has to move from an Oracle-App-Server
      to JBoss. So i created a new development-context using
      Eclipse&Jboss-Tools transfered also the ole JDevelopper
      to Eclipse.

      The migration is finished, instread of the oracle-descriptor
      now there is jboss.xml file doing the job. EAR-Build
      does create a app.ear that i am trying to deploy on my
      JBoss 4.2.2 (under Linux, with JAVA 1.6), but i do receive
      the following exception:

      11:56:32,447 WARN [ServiceController] Problem creating service jboss.j2ee:service=EjbModule,module=myAppEJB.jar
      org.jboss.deployment.DeploymentException: Missing or invalid Instance Cache (in jboss.xml or standardjboss.xml); - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: )
      at org.jboss.ejb.EjbModule.createInstanceCache(EjbModule.java:1234)
      at org.jboss.ejb.EjbModule.createStatefulSessionContainer(EjbModule.java:646)
      at org.jboss.ejb.EjbModule.createContainer(EjbModule.java:579)
      at org.jboss.ejb.EjbModule.createService(EjbModule.java:342)

      The exception seems to occur in the context of a stateful session bean.
      Thats right, my application has a couple of stateless and stateful
      session beans, that habe been configured on both descriptor file.

      Does the error indicate, that the application has problems to
      persists the data of a statefull session bean ??
      Some postings on the web inidicate, that i do have to do some
      <container-configuration> in my jboss.xml, but i do not know how ?

      Oh, there is another thing i should tell you. I do have 2 datasources,
      one of them is linked to a read-only oracle-access. When i worked
      with EJB3 i learned to map persistenc-issues in my persistence.xml
      to prevetent ambiguous object mapping, but i do not have any
      persistence.xml in my EJB2.x !!!

      Thank you in advance for any help!

          Salut mecs,

          in the meantime i switched to JBoss 4.2.3 but the problem is
          still there. From my point of view there are exaclty 2 choice
          for an explanation of this problem:

          1) I misunterstood something and overseen some <container-..>
          configurations in jboss.xml. The following posting on the
          JAVA greenhorn ranch shows a similar problem. But for any
          reason, this behaviour was clear to the author (but not me;)

          Can anybody explain me, what he talks about?
          http://www.coderanch.com/t/89576/JBoss/Missing-invalid-instance-cache-error

          2) There may be a problem with the deployment for JEE-1.3/1.4
          ear's on a JEE-5 Application server or some settings to be done,
          when you want to run that old application on a novel app server.

            Salut,

            that was my fault. In jboss.xml deployment descriptor
            i have overseen, that assigned in a stateful session bean
            the following standard setting:
            <configuration-name>Standard Stateless Sessionbean</configuration-name>

            That has in turn no instance-cache assignment in the default container
            definition. The good this is, that a started to understand the cool
            architecture of jboss.

            Thanks for your audience;-)
