Goal

Is it possible to specify multiple JNDI names for the same EJB?

It is required to have the same EJB with different JNDI names like jndiA, jndiB and jndiC. All deployed on the same
server, with the JNDI name being the only difference between each deployment.

A sample entry from the weblogic-ejb-jar.xml Deplyoment Descriptor reads:

	<weblogic-ejb-jar>
		<weblogic-enterprise-bean>
			<ejb-name>statelessSession</ejb-name>
			<jndi-name>SampleEJB</jndi-name>
		</weblogic-enterprise-bean>
		<weblogic-enterprise-bean>
			<ejb-name>statelessSession</ejb-name>
			<jndi-name>ejb20-statelessSession-SampleEJB</jndi-name>
		</weblogic-enterprise-bean>
	</weblogic-ejb-jar>

However, the following exception appears in the log file while looking up the home interface:

javax.naming.NameNotFoundException: Unable to resolve 'SampleEJB'
Resolved: '' Unresolved:'SampleEJB' ; remaining name 'SampleEJB'

The client was unable to lookup the EJBHome.SampleEJB.
