JMS is clearly the missing piece in the enterprise Java architecture, and Sun has already introduced a number of major service APIs -- JDBC (for database access), JNDI (for naming and directory services), and a Java mail API -- that are required in order to write applications that integrate across the enterprise.
JMS does not require that client code be used for asynchronous message consumption, or that it be capable of handling multiple, concurrent messages.
JMS messages sent by a Session to a Destination must be received in the order in which they were sent, so their implementations must provide for the sequencing of incoming messages.
JMS is typically implemented as a star topology hubbed to a central server.
Because JMS is usually predicated on having end-points establishing persistent connections, this represents a significant issue in terms of scaling a JMS service.
A JMS client can filter the messages it receives from, say, a topic that it is a subscriber to by specifying a selection expression that uses message property values to select which messages will actually be conveyed to the client.
