EJB (Enterprise Java Beans) - hacer el cliente

Buenas,
Soy novata en esto y tengo un problemilla. Os comento:
Servidor: Sun Application Server
Driver: mysql - java
en prueba creé un modulo ejb con entidades que al ejecutarlo me rellena la bd xo no ejecuta la clase que tiene en el cliente que es otro modulo.

El cliente tiene el main:

public class Main {

@EJB(mappedName="ejbJNDI")
static NewSessionBean n;

public static void main(String[] args) {
n.persist();
}

el error que me da es el siguiente:

com.sun.enterprise.InjectionException: Exception attempting to inject Resolved Ejb-Ref cliente.Main/n@jndi: ejbJNDI - > NewSessionBean into class cliente.Main

no sé que me falta para que se ejecute el main : supongo que será algun xml que me falta.

gracias
