public class QueueRequestor extends java.lang.Object
QueueRequestorhelper class simplifies making service requests.
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.

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
