[jboss-user] [Installation, Configuration & DEPLOYMENT] - Multiple EAR deployment not working as documented (at all !)

I have 2 EARs that I wish to deploy in the same JBoss configuration. The EARs have identical contents except for the conf/log4j.xml file, the MySQL datasource file, and the META-INF/jboss-app.xml file. One of the files in each of the EARs is a JAR file (config.jar) containing POJOs and EJBs. config.jar is in the root level of the EARs.

When I deploy the EARs I get the error:

anonymous wrote : 
  | --- MBeans waiting for other MBeans ---
  | ObjectName: jboss.j2ee:module=config.jar,uid=31702491,service=EjbModule
  |   State: FAILED
  |   Reason: javax.management.InstanceAlreadyExistsException: jboss.j2ee:jndiName=ejb/CustBean,service=EJB already registered.
This article http://www.jboss.org/community/docs/DOC-9288 and others I have found led me to make the changes:

  | myear1.ear: META-INF/jboss-app.xml
  | <jboss-app>
  |    <loader-repository>com.mycompany:loader=myear1.ear</loader-repository> 
  | </jboss-app>
  | myear2.ear: META-INF/jboss-app.xml
  | <jboss-app>
  |    <loader-repository>com.mycompany:loader=myear2.ear</loader-repository> 
  | </jboss-app>
Section of the documentation found here http://docs.jboss.org/jbossas/jboss4guide/r1/html/ch2.chapter.html confirms what I have done is correct.

In default/deploy, my ear-deployer.xml has the contents:

  | <server>
  |    <mbean code="org.jboss.deployment.EARDeployer"
  |       name="jboss.j2ee:service=EARDeployer">
  |       <attribute name="Isolated">true</attribute>
  |       <attribute name="CallByValue">false</attribute>
  |    </mbean>
  | </server>
The EARs have identical META-INF/application.xml files with contents:

  | 	<module>
  | 		<web>
  | 			<web-uri>eartest_w.war</web-uri>
  | 			<context-root>test_root_ctx</context-root>
  | 		</web>
  | 	</module>
  | 	<module>
  | 		<java>config.jar</java>
  | 	</module>
I want only one code base, and so having different JNDI names for my beans in each copy of config.jar is not something I want to do. The articles I have read suggest that what I want to do is possible, but I am clearly missing something. Any help therefore greatly appreciated!
