Hi,

  Is there a way to configure Message Driven Bean so that it doesn't process
concurrently. The problem is the onMessage function we are accessing a
resource that can be accessed by only one thread at at time (indexing data).
2 MDB's try and index data at the same time which causes problem.

The only way i can think of is having just one instance of the MDB in the
container. JBoss allows this but i am not sure of the other containers. This
will result in low through put with the messages and hamper performance.

Is there a better way to do this??

Cheers
Sachin
