I am working on a project in which we are currently using Weblogic 5.1, which uses the EJB 1.1 standard.
I am evaluating what it would take to move to Weblogic 6.0, which uses the EJB 2.0 standard.
I understand that EJB 2.0 provides for triggers directly from Java, but, what else does it give us, what problems does it create for us.

Thank you for your time and patience

Specifically for Weblogic there are RDBMS optimisations.
Allegedly, EJB2.0 is backward compatible with EJB1.1 but remember that EJB2.0 is just at the final draft stage with SUN. Weblogic have undertaken to be compatible with the final EJB2.0 specification.

It may be useful to visit the weblogic news groups (they can be accessed via the BEA home page www.bea.com)
