The desire behavior is to be able to bind an OpenEJB Resource to one or more additional names in JNDI. There is a direct benefit for me to have this feature. I'm currently in the process of integrating JBoss Cache into OpenEJB, and JBoss places its cache manager at "java:CacheManager". To avoid having two different sets of JNDI locations (in persistence.xml, for lookups in beans, etc.) it is ideal to get OpenEJB to allow the "java:CacheManager" in its JNDI to point to the real Resource at "openejb:/Resource/..."
It may be desirable to have more than one alias for a Resource, so the alias property can be a comma-separated list:
