Hi i have few doubts in ejb. these questions i faced in a interview .
1.) Can we combine both CMP Bean and BMP Bean?

2.) Can we use EB(Entity Bean) inside DAO Classes?

Eagerly waiting for answers.

Answers:
1)No
2)Yes
3)You have to select design pattrens while designing the system as per your needs(requirements),There are J2EE & EJB Design patterns available .
EJB is merely a spec. from Sun
Google around for EJB & J2EE Design Patterns
J2EE Design Patterns from Sun Site

I hope this helps.
why you have asked the same question twice?
