EJB Container initialization error : Error while binding JNDI name?

Question

Spent all day trying to get this to work with no success. Any ideas how this error can be solved?

Here are the three projects that are associated and their structures:

BasicSessionEJB.java

package ejbModule.test;

import javax.ejb.Stateless;

/**
 * Session Bean implementation class BasicSessionEJB
 */
@Stateless( mappedName="ejb/BasicSessionEJB" )
public class BasicSessionEJB implements BasicSessionEJBRemote {

    /**
     * Default constructor. 
     */
    public BasicSessionEJB() {
        // TODO Auto-generated constructor stub
    }
    public String getMessage() {
        return "Hello, EJB Wolrd!";
   }

}

BasicServlet.java

package src;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.ejb.*;
/**
 * Servlet implementation class BasicServlet
 */


public class BasicServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;

    @EJB private ejbModule.test.BasicSessionEJBRemote basicSessionEJB;

    /**
     * Default constructor. 
     */
    public BasicServlet() {
        // TODO Auto-generated constructor stub
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        try{
            PrintWriter out = response.getWriter();
            out.println("Servlet Message:" + basicSessionEJB.getMessage());
        } catch(Exception e){
             throw new ServletException (e);
        }
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        try{
            PrintWriter out = response.getWriter();
            out.println("Message:" + basicSessionEJB.getMessage());
        } catch (Exception e){
             throw new ServletException (e);
        }
    }



}

BasicSessionEJBRemote.java

package ejbModule.test;

import javax.ejb.Remote;

@Remote
public interface BasicSessionEJBRemote {
    String getMessage();
}

EJBDesktopClient.java

package appClientModule.test;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class EJBDesktopClient {

    public EJBDesktopClient() {
        // TODO Auto-generated constructor stub
    }

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
       try {
           Context ctx = new InitialContext();
           ejbModule.test.BasicSessionEJBRemote bean = (ejbModule.test.BasicSessionEJBRemote) ctx.lookup("ejb/BasicSessionEJB");
           System.out.println("Message: " + bean.getMessage());
       } catch (NamingException e) {
           e.printStackTrace();
       }
    }

}

I know this is an old thread but I think it's still very important. The solution is quite easy, in the pom.xml file of the web module you need to add the next text

<scope>provided<scope>

this is due because you already have deployed an EJB so when yo try to do it with servlet it will copy it generating the error
