Mock question regarding methods callable in MDB..

[saran ram]

Which of the following methods can the message driven bean legally call on its context?

The answers were

getUserTransaction
getCallerPrincipal

Calling getUserTransaction() is legal or what?
Please clarify.

Hi,

Only BMP MDB can call getUserTransaction() in OnMessage() method. CMP MDB can't call.
I think neither of them can call getCallerPrincipal(), because MDB don't have client.
I hope this help.
