Forgive me if this is covered in another spot.....I have searched
the forums, but did not find an article that covers this.
I'm trying to implement Brett McLaughlin's multiple-ejb
database system, with his Office, User, Fund, etc beans, and
have tried implementing them one at a time.
Got Office to work, now trying to set up User access.

This will compile, but when I deploy the jar file, it tells me
that :
10:18:08,280 ERROR [EntityContainer] Starting failed jboss.j2ee:jndiName=OfficeB
ean,service=EJB

........more.........
Don't the setType and getType methods belong in the bean if
they are going to actually do something ? I'm still a bit
confused in what belongs where, and this seems strange
that you would need to define the methods as abstract in
the bean but need to have them do work.
Thanks.....
