    JBoss AS 7.1: Remote JNDI-Call won't do any action in server bean

    Sebastian Bayerlein Newbie

      Hello,

       

      I deployed a simple EJB on a JBoss AS 7.1CR1.

       

      The logfile of the JBoss contains the information, that the bean is available with JNDI entry

      java:app/jboss.migration.example.Asterix/Asterix!com.xxxxx.example.ejb.client.AsterixHome

       

      My Java-Client-Code won't return after doing the following lookup:

      String lookupString = "ejb:app/jboss.migration.example.Asterix/Asterix!com.xxxxx.example.ejb.client.AsterixHome";
      
      
      final Hashtable<String, String> jndiProperties = new Hashtable<String, String>();
      jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
      jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.as.naming.InitialContextFactory");
      jndiProperties.put(Context.PROVIDER_URL, "127.0.0.1:4447");
      
      
      InitialContext context = null;
      try
      {
                context = new InitialContext(jndiProperties);
                AsterixHome ejbHome = (AsterixHome) context.lookup(lookupString);
      
                Method creator = ejbHome.getClass().getMethod( "create", new Class[ 0 ] );
             Asterix ejbObject = ( Asterix ) creator.invoke( ejbHome, new Object[ 0 ] );
                ...
      
      

       

      The only output in the client log is the following:

      Can someone tell me, why the invokation won't return? When canceling the lookup-client, I get the following server-log:

      15:10:39,423 ERROR [org.jboss.remoting.remote] (Remoting "ltp-cob-00-0026" read-1) JBREM000200: Remote connection failed: java.io.IOException: Eine vorhandene Verbindung wurde vom Remotehost geschlossen
      

       

      That's the config for the ejb (ejb-jar.xml):
