Non-Persistent Queue

Hi,

I'm trying to use a non-persistent queue, but when no consumer is connected
the message stays in activemq. If I connect a consumer after a while the
message is delivered.

What I want is the same logic of Topic but in a Queue, if no consumer is
connected the message is discarded.
This is because I can have 2 consumers, if the message failed to deliver to
one consumer, the message is delivered to the second one.

Kind Regards,
Nelson Cintra.
