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.
 
It is sorta covered in the JavaRanch Style Guide.
