Writing a Standalone Client for EJB 3.0 Bean For Weblogic 10

Question

Steps for Writing a Standalone Client
Client Code
package com.client;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.rmi.PortableRemoteObject;
import com.StatelessService;
public class StatelessClient {
     public static void main(String [] args){
          Context ctx = null;
          try {
               ctx = getInitialContext("t3://localhost:7001/protossbservice","weblogic","weblogic");
               Object ref = ctx.lookup("StatelessService#"+StatelessService.class.getName());
               StatelessService service = (StatelessService)PortableRemoteObject.narrow(ref,StatelessService.class);     
               System.out.println("StatelessClient.getMessage() ++");
               String  message = service.getMessage();
               System.out.println("StatelessClient.getMessage --");
                    System.out.println("Message from Bean "+message);
     } catch (NamingException e) {
               e.printStackTrace();
     private static Context getInitialContext(String url, String user, String password) throws NamingException {
        Properties h = new Properties();
        h.put(Context.INITIAL_CONTEXT_FACTORY,
                "weblogic.jndi.WLInitialContextFactory");
        h.put(Context.PROVIDER_URL, url);
        h.put(Context.SECURITY_PRINCIPAL, user);
        h.put(Context.SECURITY_CREDENTIALS, password);
        return new InitialContext(h);
Business Interface
package com;
public interface StatelessService {
     public String getMessage();
Stateless Session Bean
package com;
import javax.annotation.PostConstruct;
import javax.ejb.Remote;
import javax.ejb.Stateless;
* Test Stateless Session Bean
@Stateless(mappedName="StatelessService")
@Remote(StatelessService.class)
public class StatelessServiceBean implements StatelessService {
     public String getMessage(){
          return "I am invoked";

Hi,
I am a trainee although with a good background in java.
I'm urgently in need of a free ebook for EJB 3.0 with the latest version of Netbean. Pls, help me with one if you have. my email is [email protected]

Here's a good free e-book but without Netbean. It covers everything you would need to know about EJBs.

Again, is container managed bean good for a big project?
The question is too vague to be answered. It's a design decision that needs more details.
