I would like to know the support for EJB inheritance provided by various application servers available in the market today.
I have a little bit knowledge about websphere, and it provides support for EJB inheritance. It also gives us options for mapping parent, child EJBs using root/leaf or single table mapping. I can deploy two CMP beans with inheritance very easily on Websphere.
I would like to know whether any other application servers provide these kind of options for EJB inheritance.

We are currently using CMP EJB Inheritance with Websphere 5.1. The inheritance seems to be working, except the generated DLL does not have
integrity constraints between parent child beans. We added our constraints
and it breaks ie the websphere tries to delete the root ejb first and the go deleting towards leaf which results in constraints violation. We have submitted this bug to IBM support. Meanwhile, we have removed the constraints and it works fine.
