    Getting javax.naming.CompoundName ->Name Not Found exception

    Smitha K Newbie

      Intention of my exercise is:-

       

      To call   EJB deployed as an ear on JBOSS from a remote client.

       

      1] EJB application on JBOSS has the following structures:-

       

      a)It has  Meta-INF folder containign application.xml

      <?xml version="1.0" encoding="UTF-8"?>

      <!DOCTYPE application PUBLIC '-//Sun Microsystems, Inc.//DTD J2EE Application 1.3//EN' 'http://java.sun.com/dtd/application_1_3.dtd'>

      <application>
        <display-name>MyFirstBean</display-name>
        <description>Application description</description>
        <module>
          <ejb>ejb.jar</ejb>
        </module>
      </application>

      b) it has ejb.jar

      which has following files and meta-inf which has ejb.jar.xml

      <?xml version="1.0" encoding="UTF-8"?>
      <ejb-jar>
        <description>A simple session bean</description>
        <display-name>Simple Message EJB</display-name>
        <enterprise-beans>
          <session>
            <ejb-name>SimpleMessenger</ejb-name>
            <home>FirstEJBHome</home>
            <remote>FirstEJBObject</remote>
            <ejb-class>FirstEJBBean</ejb-class>
            <session-type>Stateless</session-type>
            <transaction-type>Container</transaction-type>
          </session>
        </enterprise-beans>
      </ejb-jar>

      c) It has jboss.xml

       

      <?xml version="1.0" encoding="UTF-8"?>
      <jboss>
        <enterprise-beans>
          <session>
            <ejb-name>FirstEJBBean</ejb-name>
            <jndi-name>FirstEJBTrySM</jndi-name>
          </session>
        </enterprise-beans>
      </jboss>

       

      d)And it has FirstEJBBean.class

      FirstEJBHome.class

      FirstEJBObject.class

       

      It has successfully deployed my ejb on jboss but the  jndi bindign has not happened.

      While starting jboss server,it  gives this exception on the server.

      e) I am trying to call the  above EJB from remote client.

       

      I created a class FirstEJBClient with the following code:-

      import java.rmi.RemoteException;
      import java.util.Hashtable;

      import javax.ejb.CreateException;
      import javax.ejb.EJBException;
      import javax.ejb.EJBHome;
      import javax.ejb.EJBObject;
      import javax.ejb.SessionBean;
      import javax.ejb.SessionContext;
      import javax.naming.Context;
      import javax.naming.InitialContext;
      import javax.naming.NamingException;
      import javax.rmi.PortableRemoteObject;

      public class FirstEJBClient  {

      public static void main(String args[])
      {
       
      try {
       
        Hashtable environment = new Hashtable();
              environment.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
              environment.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
              environment.put(Context.PROVIDER_URL, "jnp://172.16.84.66:1099"); // remote machine IP
              InitialContext context = new InitialContext(environment);
              Object obj = context.lookup("FirstEJBTrySM"); //ejb-name
              System.out.println("-->> lookup object successfully");


             
        FirstEJBHome ejbHome = (FirstEJBHome) PortableRemoteObject.narrow(obj,EJBHome.class);
        try {
         FirstEJBObject firstEJBObject =(FirstEJBObject) ejbHome.create();
         firstEJBObject.firstHello();
        
        } catch (RemoteException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
        } catch (CreateException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
        }

       

       

      } catch (NamingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      }

       

       

      }
      }

       

      Getting look up issue. It says at this line:-    Object obj = context.lookup("FirstEJBHome"); //ejb-name
