Embedding a Message Queue Broker in a Java Client

Message Queue supports running a broker from within a Java client. Such a broker, called an embedded broker, runs in the same JVM as the Java client that creates and starts it.

Beyond operating like a normal standalone broker, an embedded broker offers the application in which it is embedded access to a special kind of connection called a direct mode connection. Direct mode connections are used just like ordinary connections, but they are much higher performing because they use in-memory transport instead of TCP. To specify a direct mode connection, the client specifies mq://localhost/direct as the broker address in the connection factory from which it subsequently creates the connection.
