Hi all,
i have a theoretical questions. When i have three CMP objects
within one transaction how many connections are allocated from
the connection pool ? Is it only one connection object which is
shared by the CMP's or are there three connections ?
(BTW: I am talking of EJB 2.0)
Thx in advance

This is managed by the Container, so it is really implementation dependent. In other words it is not mandated by the EJB Specification. However, I would think that given the fact that they are all part of the same transaction then they would likely use the same connection.
I agree. Here's the link:
