My impression (not based on any inside info whatsoever) is that the
MEJB was introduced largely because for some reason the jsr77 spec
team didn't want to require jmx in j2ee -- this was well before jmx
was added to j2se. I don't see any problem using jmx for monitoring
geronimo servers. If we want to be able to also monitor other
servers we could keep the MEJB-using code around for that purpose.
my opinion :-)
