public class QueueRequestor extends Object
QueueRequestor helper class simplifies
making service requests.
The QueueRequestor constructor is given a non-transacted
QueueSession and a destination Queue. It creates a
TemporaryQueue for the responses and provides a
request method that sends the request message and waits
for its reply.
This is a very basic request/reply abstraction which assumes the session is non-transacted with a delivery mode of either AUTO_ACKNOWLEDGE or DUPS_OK_ACKNOWLEDGE. It is expected that most applications will create less basic implementations.

with a delivery mode of either AUTO_ACKNOWLEDGE or
DUPS_OK_ACKNOWLEDGE.

QueueRequestor and its session.
Since a provider may allocate some resources on behalf of a
QueueRequestor outside the Java virtual machine, clients
should close them when they
are not needed. Relying on garbage collection to eventually reclaim
these resources may not be timely enough.
Note that this method closes the QueueSession object
passed to the QueueRequestor constructor.
