JMSPublisher is a JMS message consumer that publishes messages to a JMS Topic. It receives JMS messages from the internal XQueue and delivers them to the topic destination. JMSPublisher supports all JMS implentations via JNDI. Only one operation, pub, is supported for now. It also supports flow control and XA. Fault tolerance with auto reconnections is built in.

Apart from the common properties, there are many implementation specific properties for JMSPublisher.
