NamingContext

[Akhil Maharaj]

Hi ,

I am relatively new to this . But I think I have spent more than 10 hours googling . My goal is to run my first EJB3.0 . I have taken the code from
Ch4 of Oriely Mastering EJB3.0 5th edition. I am using Ant and JBoss 4.2.2

First Thing is ant task compile is ok .
Even deploy task is also happening OK . I can see the titan.jar in the deploy direcotry . However , It is not listed in the jmx_console.

Second thing is after titan.jar is deployed to Jboss , I am running the client , Thats where I am getting this exception .

Here is the client code

  
 
package com.titan.clients;
 
import com.titan.travelagent.TravelAgentRemote;
import com.titan.domain.Cabin;
 
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;
import java.util.Properties;
import javax.rmi.PortableRemoteObject;
 
public class Client {
    public static void main(String [] args) {
        try {
            Context jndiContext = getInitialContext( );
 

 
            Object ref = jndiContext.lookup("TravelAgentBean/remote");
 

 

            TravelAgentRemote dao = (TravelAgentRemote)
                PortableRemoteObject.narrow(ref,TravelAgentRemote.class);
 
            Cabin cabin_1 = new Cabin( );
            cabin_1.setId(1);
            cabin_1.setName("Master Suite");
            cabin_1.setDeckLevel(1);
            cabin_1.setShipId(1);
            cabin_1.setBedCount(3);
 
            dao.createCabin(cabin_1);
 
            Cabin cabin_2 = dao.findCabin(1);
            System.out.println(cabin_2.getName( ));
            System.out.println(cabin_2.getDeckLevel( ));
            System.out.println(cabin_2.getShipId( ));
            System.out.println(cabin_2.getBedCount( ));
 
        } catch (javax.naming.NamingException ne){ne.printStackTrace( );}
    }
 
    public static Context getInitialContext( )
        throws javax.naming.NamingException {
 
        Properties p = new Properties( );
 
        //jndiContext.addToEnvironment("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
//jndiContext.addToEnvironment("java.naming.factory.url.pkgs", "org.jboss.naming,org.jnp.interfaces");
//jndiContext.addToEnvironment("java.naming.provider.url","localhost:8080");
        // ... Specify the JNDI properties specific to the vendor.
 
           p.put(Context.INITIAL_CONTEXT_FACTORY,
           "org.jnp.interfaces.NamingContextFactory");
       p.put(Context.URL_PKG_PREFIXES,
           " org.jboss.naming :-o	 rg.jnp.interfaces");
       p.put(Context.PROVIDER_URL, "jnp://localhost:1099");
 

        return new javax.naming.InitialContext(p);
    }
}
 

 

Another thing that is puzzling me is what is the meaning of messages that I see ( the following) on the console ,

 
 
-- MBeans waiting for other MBeans ---
ObjectName: jboss.j2ee:jar=titan.jar,name=TravelAgentBean,service=EJB3
  State: NOTYETINSTALLED
  I Depend On:
    persistence.units:unitName=titan
 
--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: persistence.units:unitName=titan
  State: NOTYETINSTALLED
  Depends On Me:
    jboss.j2ee:jar=titan.jar,name=TravelAgentBean,service=EJB3

Looks like the application is not deployed successfully. The actual error messages will be somewhere above these few lines of exception. Post that exception stacktrace here. That might give us a clue.
