Hi,

   I am having a problem with EJB 3.0 . I am using 
EJB-3.0_RC9-FD 
jboss-4.0.4.GA 
jdk 1.5
ant 1.6.5
I am using the hypersonic database of jboss and I want to create  two tables in the database Department and Emplyee.


The code for client.java

package com.abcd.EJB3.application;

import com.infosys.EJB3.application.FacadeRemote;
import javax.naming.InitialContext;
import java.sql.Timestamp;

public class client
{
   public static void main(String[] args)
   {
 	try
 	{
 	  InitialContext ctx = new InitialContext();
      FacadeRemote lFacadeRemote = (FacadeRemote) ctx.lookup(FacadeRemote.class.getName());

	  lFacadeRemote.createDepartment("Finance");
	  lFacadeRemote.createDepartment("Administration");
	  lFacadeRemote.createDepartment("Sales");

	  lFacadeRemote.assignEmployeeToDepartment(new Long(1),"Brijesh",31,"M");
	  lFacadeRemote.assignEmployeeToDepartment(new Long(1),"xxxx",31,"M");
	  lFacadeRemote.assignEmployeeToDepartment(new Long(2),"yyyy",31,"M");

 	}
 	catch(Exception ex)
 	{

code for FacadeBean 

package com.abcd.EJB3.application;

import javax.ejb.Stateless;
import javax.ejb.Remote;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import com.infosys.EJB3.application.Department;
import com.infosys.EJB3.application.Employee;

import java.util.Set;

@Stateless
public class FacadeBean implements FacadeRemote
{
   @PersistenceContext
   private EntityManager manager;

   public void createDepartment(String deptName)
   {
	    Department department = new Department();

		department.setName(deptName);

		manager.persist(department);

   }

   public void assignEmployeeToDepartment(Long id, String name, int age, String sex)
   {
	    Department department = searchDepartment(id);

		department.addEmployee(name, age, sex);

		manager.persist(department);
   }

   public Department searchDepartment(Long id)
   {
		return manager.find(Department.class,id);
   }

}


code for FacadeRemote


package com.abcd.EJB3.application;

import javax.ejb.Remote;

@Remote
public interface FacadeRemote
{
	public void createDepartment(String deptName);
	public Department searchDepartment(Long id);
    public void assignEmployeeToDepartment(Long id, String name, int age, String sex);
}



now I have compiled the code and deployed it. But when I try to run the code I get the following error:


NameNotFoundException  ----- FacadeRemote not bound.

I think its something related to JNDI binding.. but here since I am using EJB 3.0, i dont have to use ejb-jar.xml, but then how does this happens?? what should I do... Please help....
