Hi Ajith,
No, the EJB spec defines JMS MDBs as being associated with a single
Queue or Topic at
deployment time. The exact configuration for expressing the
association is considered
vendor-specific, but the current spec considers the association to be
fixed, in much the same
way that a persistence unit is associated with a particular database for
the duration of an
application's deployment.
A Java EE implementation could support such a feature but it would not
be considered
portable.
