    accessing EJB deployed on JBoss5.1 at a remote server using AS7 client

    Uday Shankar Newbie


      I am trying to access an EJB deployed on a remote server (AIX machine) from a Java client which has a main method.

      the code I am using is below:


      public static void main(String[] args) {

              Properties p = new Properties();


              p.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");//AS7

              p.put(Context.PROVIDER_URL, "jnp://d05leapp02:1299");//server running on 8280, and host is d05leapp02


              try {

                         //bean name is dgin.ol.cs.bo.sb.dbaccess.DBAccessorBean_jndi

                Context c = new InitialContext(p);

                //ear_name=MTApp.ear; jar_name=dbaccess.jar; Bean_name=DBAccessorBean

                String lookupJndi = "ejb:MTApp/dbaccess//DBAccessorBean!" + DBAccessor.class.getName();


                Object home_obj = c.lookup(lookupJndi);


                DBAccessorHome home = (DBAccessorHome) PortableRemoteObject.narrow(home_obj, DBAccessorHome.class);

                DBAccessor dba_bean = home.create();


              } catch (Exception e) {







      when executing this code I get ClassCastException, as below:

      May 25, 2012 2:59:28 PM org.jboss.ejb.client.EJBClient <clinit>

      INFO: JBoss EJB Client version 1.0.2.Final

      Caused by: java.lang.ClassCastException: $Proxy0 cannot be cast to org.omg.CORBA.Object

          ... 3 more


      Note: I have the jboss-client-7.1.0.Final.jar in the class path

      any help is appriciated. thanks in advance.
