Assuming the auto-id is your primary key, what would
you use as the entity bean's primary key?

Hi all,
while we all in this list have debated about the
best way to have an Autoincrement-like feature in our EJB (using AutoNumber
bean, using a singleton session bean to retrieve the newly created id in the
db, etc.), i've just came through a text at jGuru - in FAQ section about EJB -
about a fairly simple way to handle auto-incr with CMP. I'd just like want to
know if anyone has tested the suggested method, and if it works correctly with
jBoss ....
Any comment would be higly
appreciated.

How does Container
Managed Persistence work with automatically generated database ID
fields? Should I map the ID field explicitly or leave it unspecified?

Answer
In the Deployment Descriptor,
map the normal fields appropriately, but don't specify the auto-id field as
one of the container managed fields.
