Yes ..
JMQ2.0 will support 3 types of queue's:
* single queue receiver (similar to the current 1.1 behavior)
only 1 receiver can be active at a given time on a queue
* failover : multiple queue receivers can be active at a given
time but only one receiver is receiving messages. When the "active"
receiver is closed, the next receiver registered starts receiving
messages
* round-robin : messages are sent equally to all active queue receivers.
In this type of queue, messages are not guarenteed to arrive in order
(since messages to a receiver may need to be resent to a different
receiver when it is closed)
You can configure the type of queue either through the admin tool when the
queue is created or by setting the default type for autocreated (not
created by an administrator) queues
