This section introduces the core API entities and describes how they operate together.

AMQ OpenWire JMS sends and receives messages. Messages are transferred between connected peers using message producers and consumers. Producers and consumers are established over sessions. Sessions are established over connections. Connections are created by connection factories.

A sending peer creates a producer to send messages. The producer has a destination that identifies a target queue or topic at the remote peer. A receiving peer creates a consumer to receive messages. Like the producer, the consumer has a destination that identifies a source queue or topic at the remote peer.

A destination is either a queue or a topic. In JMS, queues and topics are client-side representations of named broker entities that hold messages.

A queue implements point-to-point semantics. Each message is seen by only one consumer, and the message is removed from the queue after it is read. A topic implements publish-subscribe semantics. Each message is seen by multiple consumers, and the message remains available to other consumers after it is read.

See the JMS tutorial for more information.
