Hi,

I read in some article that BMP is not supported in EJB 3.0. My first Question why it was decided to discontinue support for BMP, and other doubt is what if an old multi JVM application using BMP and upgraded to EJB3 compatiable application server then it means code need to be upgraded to remove BMP from code.

This is not true. The same BMP (and everything else) that was supported in EJB 2.1 is still supported in the traditional entity bean component in EJB 3.0.

Note that there is no notion of BMP or CMP in JPA, though. No changes need to be made to existing code in order to make it work in EJB 3.0 containers.
