<P>You can use this technique for example to be able to watch a queue, by
sending messages sent to a queue to a notification topic.</P>

destinations</H3>
+
+<P>From Apache ActiveMQ <B>4.2</B> onwards you can now use selectors to define
virtual destinations.</P>
+
+<P>You may wish to create a virtual destination which forwards messages to
multiple destinations but applying a selector first to decide if the message
really does have to go to a particular destination.</P>
+
+<P>The following example shows how a message sent to the virtual destination
<B>MY.QUEUE</B> will be forwarded to <B>FOO</B> and <B>BAR</B> if the selectors
match</P>

-<P>Yes. You have to make sure that the messages sent to the
'Consumer.*.VirtualTopic.>' destination are not forwarded. This
can be done by configuring the network connector something like:</P>

Duplicate Message in a Network of Brokers</H2>
-<P>If you use Virtual Topics in a network of brokers, it is likely you will
get duplicate messages if you use the default network configuration. This is
because a network node will not only forward message sent to the virtual topic,
but also the associated physical queues. To fix this, you should disable
forwarding messages on the associated physical queues. </P>
