Introduction

Referring to beans from other Jar not included in the same Ear is not as simple as in case they are included in one Ear. There are three ways to accomplish this purpose.

Jar with referred bean

Java code

@Stateless(name="JmsDispatcherGate")
public class JmsDispatcherGateImpl implements DispatcherGateLocal, DispatcherGateRemote {

@Local
public interface DispatcherGateLocal {

@Remote
public interface DispatcherGateRemote {

Geronimo's specific XML

<?xml version="1.0" encoding="UTF-8"?>
<openejb-jar xmlns="http://www.openejb.org/xml/ns/openejb-jar-2.1" xmlns:pkgen="http://www.openejb.org/xml/ns/pkgen-2.0" xmlns:sec="http://geronimo.apache.org/xml/ns/security-2.0" xmlns:sys="http://geronimo.apache.org/xml/ns/deployment-1.2">

Referring with @EJB(mappedName="...") + openejb-jar.xml

package my.app.services;

@Stateless(name = "Sender")
public class SenderImpl {

	@EJB(mappedName="Dispatcher/JmsDispatcherGate")
	private DispatcherGateRemote dispatcherGate = null;

Referring with @EJB(name="") + openejb-jar.xml

package my.app.services;

@Stateless(name = "Sender")
public class SenderImpl {

	@EJB(name="dispatcher")
	private DispatcherGateRemote dispatcherGate = null;
