The EJB service provides simplified logical lookup of EJBHome
objects for access inside and outside of a container environment.
InitialContext settings are externalized into a configuration file
so they may be updated without changes to the code. It also
removes the need to repeat the RMI narrowing code of remote
EJBHome lookups.
The service is especially useful when EJBs will be accessed from
inside and outside a J2EE container as well as when different
context factories need to be used to access remote beans on
multiple servers.
