FAQ > JMS > Can I send and receive messages concurrently on one JMS Connection
Absolutely!
Strictly speaking each producer being used concurrently should be using a separate session (though in ActiveMQ it'll probably work fine if you just use one session for all publishers).
For concurrent consumption create a session per consumer - as all messages are dispatched to a session in a single thread - but you can have as many sessions as you like per connection.
To further help with concurrent consuming of JMS you can use Message Driven POJOs
