Jboss is built on top of RMI, so it uses by default JRMP. Feature to enable
it to use another protocol than JRMP is not yet implemented, AFAIK (i'm not
personnaly an active developper of jboss, so don't know it it's on the to-do
list or not ...)

Hi Grant,
Set the login attribute to true to get more information on what's happening.
NullPointer is returned from the pool if it cannot create a connection to
the database for any reason.
Verify that you start the postmaster with the -i flag, wich enables network
connection to the database
I meant the LoggingEnabled attribute in the pool conf

Hi
IMHO, I think this is more Linux problem than a EJB one. But this problem
of Linux spawning thousand of threads has been raised many times, but i
could not find on the list a final solution to fix this. Can anyone post a
sort of HOW-TO to overcome this problem on a production environment ?
Thanx
You don't need to do this in a finder method ... just do it in a normal
business method, wich return an int or an Integer object (the result of the
'select count' query ...)

Remove all EJBException from the throws clause of ALL of your business

declare EJBException in its throws clause, then that remote interface
