That's one way to do it.

Yeah, since this service (and many others) bind themselves into JNDI you
will have conflicts if you run one JNDI with several servers.
A better way to do it is to let each server have its own JNDI, and use
ejb-references in your beans to locate them. Then use jboss.xml to map
an ejb-reference to a complete JNDI name, e.g. let
"java:comp/env/ejb/MyEjb" map to "jnp://somehost/myapp/MyEjb". This way
you will have to configure the deployment descriptors for each bean, but
the bean source can use the hardcoded "java:" names.
