>From the beginning the existing container system for ejb was used as a
convinient method to implement MDB in the JBoss container system. The
contract all was done according with was that no one was ever allowed to
get the remote and home interfaces of an MDB. That it at al was
theoretically possible to do this was because the MDB container inherited
from a "fat" contianer with more methods that was actually needed by the
MDB. I therefore made all these methods throw a runtime exception to
really mark theses methods as "hands of".
This was never discussed on the list, it was just my descission. Mybe it
is not needed any more...since all now is aware of that there are an MDB
container wich the container developers have to acknowledge (the latest
problem does not ver ify this however).
