    I can't get localhome in jboss! Help me!

    calffin Newbie

      I use lomboz for eclipse to develop a CMPBean which is deployed in jboss3.0.8. The jboss uses the configuration files under server/all directory ,not server/default , in my eclipse. The CMPBean named Account should be deployed successfully because the information below emerged when starting the jboss under eclipse :

      23:41:45,593 INFO [MainDeployer] Starting deployment of package:
      file:/D:/jboss-3.0.8/server/all/deploy/TicketModule.jar
      23:41:45,781 INFO [EjbModule] Creating
      23:41:45,812 INFO [EjbModule] Deploying Account
      23:41:45,875 INFO [EjbModule] Created
      23:41:45,875 INFO [EjbModule] Starting
      23:41:47,703 INFO [Account] Table 'ACCOUNT' already exists
      23:41:47,750 INFO [EjbModule] Started
      23:41:47,750 INFO [MainDeployer] Deployed package:
      file:/D:/jboss-3.0.8/server/all/deploy/TicketModule.jar


      I think the clue above means that the CMPBean is deployed in jboss. To test the CMPBean I write a plain java object (not a sessionBean) in the same project where the CMPBean resides. The main function of the plain java object is to retrive the localhome of the CMPBean and call the FINDER mothed. But I find that I can't get the localhome refrence through the getLocalhome() in the AccountUtil class generated by lomboz . I write the code to throw an EJBException which inherites the RuntimeException when error occured. The real Exception is nested in the EJBException so I can stop the application and find what the real error is .I find that if I use the default code in the getLocalHome() which is listed below:
      javax.naming.InitialContext initialContext =new javax.naming.InitialContext();
      (server.ejb.account.AccountLocalHome)initialContext.lookup(server.ejb.account.AccountLocalHome.COMP_NAME)

      I 'll get the error below:

      javax.ejb.EJBException: nested exception is: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
      javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:
      java.naming.factory.initial at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:640)


      If I change the default code to the format below:
      Hashtable props = new Hashtable();
      props.put(
      javax.naming.InitialContext.INITIAL_CONTEXT_FACTORY,
      "org.jnp.interfaces.NamingContextFactory");
      props.put(
      javax.naming.InitialContext.PROVIDER_URL,
      "jnp://127.0.0.1:1099");
      // Obtain initial context
      javax.naming.InitialContext initialContext =
      new javax.naming.InitialContext(props);
      (server.ejb.account.AccountLocalHome)initialContext.lookup(server.ejb.account.AccountLocalHome.COMP_NAME)

      I'll get the erro below:
      javax.ejb.EJBException: nested exception is: javax.naming.NameNotFoundException: comp not bound

      If I change the "server.ejb.account.AccountLocalHome.COMP_NAME"(which is "java:comp/env/ejb/Account") to "server.ejb.account.AccountLocalHome.JNDI_NAME" (which is"
      Account"), I 'll get the error below :
      exception is java.lang.ClassNotFoundException: org.jboss.ejb.plugins.local.LocalHomeProxy
      (no security manager: RMI class loader disabled)]
      javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException:
      org.jboss.ejb.plugins.local.LocalHomeProxy (no security manager: RMI class loader
      disabled)]


      I am surprise very much. I write code to list all the content in the Context
      NamingEnumeration enum = initialContext.list("");
      // print out everything in the enum
      while (enum.hasMore()) {
      Object obj = enum.next();
      NameClassPair entry =
      (NameClassPair) javax.rmi.PortableRemoteObject.narrow(obj,
      NameClassPair.class);
      String eName = entry.getName();
      String eClass = entry.getClassName();
      System.out.println(eName + "\t" + eClass);}

      I get the information below:
      HASessionState org.jnp.interfaces.NamingContext
      jmx org.jnp.interfaces.NamingContext
      clustering org.jnp.interfaces.NamingContext
      ConnectionFactory org.jboss.mq.SpyConnectionFactory

      ejb org.jnp.interfaces.NamingContext
      jmx:yx:rmi org.jboss.jmx.adaptor.rmi.RMIAdaptorImpl

      I find that the AccountLocal and AccountBean are all in the Context .But I can't retrive the AccountLocal through NamingService in jboss.
      Can anybody tell me what's wrong with my application .The default code generated by lomboz is right or not ? Why can't I get the localhome refrence of Account? How should I do ? What is the right code to retrive the localhome in the same project where the EJB reside?
      I am looking forward to reply !

      Thank you a million!
      Best regards!
