The J2EE Connector architecture defines the "standard message provider
pluggability contract" that allows a JMS implementation [like Swift MQ] to be
plugged into a J2EE 1.4 or above compatible application server [like Sun's
Application Server or GlassFish]
http://java.sun.com/j2ee/connector/overview.html#4
So, though a CF/Destination could be used to send a message from an application
component, by default, an AS implementation would only send the JMS message to
the message provide it comes with [Glassfish comes with OpenMQ (Sun's
MessageQueue implementation)]. In order to integrate a 3rd party JMS provider to
an application server, in a portable a connector needs to be used.

Swift MQ has to provide its own adapter, because they could leverage their
custom protocols/APIs to communicate with their product implementation. However,
if a JMS provider does not provide a resource adapter, a generic RA like Generic
RA
http://genericjmsra.dev.java.net, that leverages the JMS implementation of
the product, could be used.
