another way around this issue?? Currently we distribute the war to our 3 app

It may have some of the info you are looking for. Also supposedly, in an
upcoming EJB3 release the value of the partition will default to
jboss.partition.name so that you can have the same ejb clustered in

There is no way to do this that is ejb3-spec compliant, however, you can use
