Problemas ao fazer lookaps com ejb3

Beleza galera?
Estou fazendo um exemplo de ejb3 mas estou tendo problemas ao fazer lookups no meu session bean.
O erro é:

javax.naming.NameNotFoundException&#58; CalculatorBean not bound

Meinha interface remota:

package interfaces;

import javax.ejb.Remote;

@Remote
public interface Calculadora &#123;
	public static final String JNDI_NAME = "CalculatorBean";
	long fatorial&#40;int n&#41;;
&#125;

Meu bean

package bean;

import interfaces.Calculadora;

import javax.ejb.Stateless;

@Stateless&#40;mappedName="CalculatorBean"&#41;
public class CalculadoraBean implements Calculadora &#123;

	public long fatorial&#40;int n&#41; &#123;
		if &#40;n &lt; 0&#41; throw new IllegalArgumentException&#40;&#41;;
		return n == 0 ? 1 &#58; n * fatorial&#40;n - 1&#41;;
	&#125;

&#125;

Estou usando java 6 e o jboss 4.2. Obrigado!

Consegui resolver o problema!
Existe 2 anotations

@RemoteBinding&#40;jndiBinding="CalculadoraRemote"&#41;
@LocalBinding&#40;jndiBinding="Calculadoralocal"&#41;

Com esses anottations eu consigo injetar um nome de binding para o meu ejb, ai o meu cliente pode acessar os meus ejbs com os nomes definidos nesses anotations.
O único problema é quando se define o mesmo nome para o local e para o remoto, neste caso deve se colocar após o nome do ejb o /remote ou o /local:

@RemoteBinding&#40;jndiBinding="Calculadora/remote"&#41;
@LocalBinding&#40;jndiBinding="Calculadora/local"&#41;

E o cliente deve acessar com o nome do ejb com o /local ou remoto:

Calculadora calculadora = &#40;Calculadora&#41; ctx.lookup&#40;"Calculadora/remote"&#41;;

Agora só falta eu aprender timer bean
Mas isso funciona em qualquer servidor j2ee
Valeu pela ajuda gelera!
