ejb-ref lookup does not work with JBoss 4.2.0GA _CP07, pleas help.

[Emanuele Ghe]

Hi,
I am using JBoss 4.2 with ear-isolation = true and call-by-value=false

I have the following situation:

ejb A needs to call ejb B, and both are in different isolated EARs.

To do this, as stated on the JBoss community wiki's:

http://www.jboss.org/community/wiki/classloadingconfiguration

I have to configure ejb-jar.xml and jboss.xml of ejb A with references to ejb b.

So, these are my configuration files:
ejb A = TISService
ejb B = GTSService

ejb-jar.xml of ejb A

...
<enterprise-beans>
		<session>
			<display-name>TISService</display-name>
			<ejb-name>TISService</ejb-name>
			<home>it.ltm.ca.tis.session.TISServiceHome</home>
			<remote>it.ltm.ca.tis.session.TISServiceRemote</remote>
			<local-home>it.ltm.ca.tis.session.TISServiceLocalHome</local-home>
			<local>it.ltm.ca.tis.session.TISServiceLocal</local>
			<ejb-class>it.ltm.ca.tis.session.TISServiceBean</ejb-class>
			<session-type>Stateless</session-type>
			<transaction-type>Container</transaction-type>

			<!-- RIFERIMENTO AL GTS -->
			<ejb-local-ref>
				<ejb-ref-name>ejb/KCP_GTSServiceLocalReference</ejb-ref-name>
				<ejb-ref-type>Session</ejb-ref-type>
				<local-home>it.ltm.kcp.gts.session.GTSServiceLocalHome</local-home>
				<local>it.ltm.kcp.gts.session.GTSServiceLocal</local>
			</ejb-local-ref>
			
		</session>
...

jboss.xml of ejb A

...
<jboss>
	<enterprise-beans>
		<session>
			<ejb-name>TISService</ejb-name>
			<jndi-name>ejb/TISService</jndi-name>
			<local-jndi-name>java:/ejb/TISService</local-jndi-name>
			
			<!-- RIFERIMENTO AL GTS -->
			<ejb-local-ref>
				<ejb-ref-name>ejb/KCP_GTSServiceLocalReference</ejb-ref-name>
				<local-jndi-name>java:/ejb/KCP_GTSService</local-jndi-name>
			</ejb-local-ref>			
		</session>
...

This is the code I am using to lookup ejb B from a class in ejb A (taken from an example in the JBoss UserGuide):

Context ctx = (Context) new InitialContext().lookup("java:comp/env"
GTSServiceLocalHome local = (GTSServiceLocalHome) ctx.lookup("ejb/KCP_GTSServiceLocalReference"); //I am using the <ejb-ref-name> as the lookup String.
GTSService instance = local.create();

The problem is that the lookup fails.

If I try to lookup the JNDI name of the EJB, the lookup succeed, but the create fails with "Invalid invocation, check your deployment..." because it is trying to create an instance of ejb B that is in an isolated ear.


Can someone help me?

Why the lookup of the ejb-ref-name fails, even if I saw that is present in the JNDI tree of ejb A ?
JNDI tree view from JMX console:

...
Ejb Module: CA_TerminalInteractionSystemEJB.jar

java:comp namespace of the TISService bean:

  +- HandleDelegate (class: org.jboss.proxy.ejb.handle.HandleDelegateImpl)
  +- ORB (class: org.jacorb.orb.ORB)
  +- env (class: org.jnp.interfaces.NamingContext)
  |   +- ejb (class: org.jnp.interfaces.NamingContext)
  |   |   +- KCP_GTSServiceReference[link -> ejb/KCP_GTSService] (class: javax.naming.LinkRef)
  |   |   +- KCP_GTSServiceLocalReference[link -> java:/ejb/KCP_GTSService] (class: javax.naming.LinkRef)
...

Am I doing something wrong?

Thanks.
