fierst of all sorry for my english :).
1.Eclipse Version: 3.1.0
2.jboss-4.0.4.GA
3.Ejb 3.0

there is my simple example :
1.Remote Interface

package org.jboss.tutorial.stateless.bean;

import javax.ejb.Remote;

@Remote
public interface CalculatorRemote {
   public int add(int x, int y);
   public int subtract(int x, int y);
}

2.Local Interface

package org.jboss.tutorial.stateless.bean;
import javax.ejb.Local;

@Local
public interface CalculatorLocal extends CalculatorRemote
{
   public int add(int x, int y);
   public int subtract(int x, int y);
}

3.Bean

package org.jboss.tutorial.stateless.bean;
import javax.ejb.Stateless;
import org.jboss.tutorial.stateless.bean.CalculatorRemote;

public @Stateless
class CalculatorBean implements CalculatorRemote {
   public int add(int x, int y) {
      return x + y;
   }
   public int subtract(int x, int y) {
      return x - y;
   }
}

4. and Client

package org.jboss.tutorial.stateless.client;

import org.jboss.tutorial.stateless.bean.CalculatorRemote;
import javax.naming.InitialContext;

public class Client
{
   public static void main(String[] args) throws Exception
   {
      InitialContext ctx = new InitialContext();
      CalculatorRemote calculator = (CalculatorRemote) ctx.lookup("CalculatorBean/remote");
      System.out.println("1 + 1 = " + calculator.add(1, 1));
      System.out.println("1 - 1 = " + calculator.subtract(1, 1));
   }
}

then in eclipse ide i did project jar file using export and copy it in the
jboss_home/server/all/deploy folder
then start jboss from eclipse
when i’m running client a get an error like that :

Exception in thread “main” javax.naming.NameNotFoundException: CalculatorBean not bound

is there enything wrong ?

Yes, you’ve made a syntactical error.

When looking the bean up via JNDI you need to specify EarProjectName/BeanName/local (or remote in your case).

Try this:
InitialContext ctx = new InitialContext();
CalculatorRemote calculator = (CalculatorRemote) ctx.lookup(“MyEarProjectName/CalculatorBean/remote”);

Substitute “MyEarProjectName” with the name of your enterprise project.

Also, why does your local interface derive from your remote interface? You should use just one or the other on the bean implementation.

HI ,
What you said i have done the same thing but still i m facing the same problem.

Step 1:

InitialContext ctx = new InitialContext();
Calculator calculator = (Calculator) ctx.lookup(“CalculatorBean/remote”);

System.out.println(“1 + 1 = ” + calculator.add(1, 1));
System.out.println(“1 – 1 = ” + calculator.subtract(1, 1));

i got following error :

Step 2:

System.out.println(“1 + 1 = ” + calculator.add(1, 1));
System.out.println(“1 – 1 = ” + calculator.subtract(1, 1));

then i got following error :

Here i have made sampleproject.jar file and uploaded on all/deploy folder.

Please suggest me.
