How can i config module and application name for JNDI Lookups

In EJB 3.1 JNDI Lookups can be made with different Lookup-Names:

java:global[/<app-name>]/<module-name>/<bean-name>!<fully-qualifiedbean interface-name>           
java:global[/<app-name>]/<module-name>/<bean-name> 
java:app/<module-name>/<bean-name>!<fully-qualified-bean-interface-name> 
java:app/<module-name>/<bean-name> 
java:module/<bean-name>!<fully-qualified-bean-interface-name> 
java:module/<bean-name>

In my JavaEE 6 Project (with Maven 2, Netbeans 6 and Glassfish v3) the Application name is X-Snapshot.ear and the EJB-Module is Y-Snapshot.jar. How can i config this maven project to use another application and module name? I don't wnat to change all JNDI Lookups when this names change!! So is it possible to config application and module names for JNDI LookUps?

Naive approach

The Maven EAR Plugin allows to Customize A Module Filename and you can set the final name or the EAR using project.build.finalName.

Much better approach

Override the <application-name> and the <module-name> in the application.xml and the ejb-jar.xml respectively. Quoting Portable Global JNDI name in EJB 3.1:

In addition to the above name, if the EJB exposes just a single client view (that is it implements just one interface or the no interface view), the container is also mandated to map the bean to

java:global/[<application-name>]/<module-name>/<bean-name>

Where

  1. <aplication-name> defaults to the bundle name (.ear file name) without the bundle extension. This can be overridden in application.xml. Also, <application-name> is applicable only if the bean is packaged inside a .ear file.
  2. <module-name> defaults to bundle name (.war or .jar) without the bundle extension. Again, this can be overridden in ejb-jar.xml.
  3. <bean-name> defaults to the unqualified class name of the bean. However, if @Stateful or @Stateless or @Singleton uses the name attribute, then the value specified there will be used as the bean name.
