yes you are right...
EJBs are location independent; you do not need to know where a bean resides, you just need to be able to connect to a node in the application server, request the bean, and then use it, not knowing its location. This requires some 'catalog' to tell the server where a bean lives such as a JNDI service.

web container(web server support cluster, it mean same contents backup to different server to support failover, in case of one web server failture, another one can take over the task)
but for wls web container/tomcat, it support RMI, but not EJB.

ejb support distribution, it mean different content (object)
located in different server(especially ejb object), so one oject can call another object located in another machine.
is it right?
