I have a doubt whether Message-driven beans may be single-threaded or multi-threaded.

I accept with Dogra.
But I could remember the spec MDB should be NON-REENTRANT It is responsibilty of Bean provider. (session beans as same).

Entity beans can be Both REENTRANT or NON- REENTRANT

REENTRANT- means Multiple Thread activity
NON-REENTRANT means Single Thread activity.

If you asking regarding to the exam.
It Should be single thread .. PLS refer MSG bean section of the Spec.
