Reference: Source and Target Connection Factories
33.2. Source and Target Connection Factories The source and target connection factory factories are used to create the connection factory used to create the connection for the source or target server. The configuration example above uses the default implementation provided by HornetQ that looks up the connection factory using JNDI. For other Application Servers or JMS providers a new implementation may have to be provided. This can easily be done by implementing the interface org.hornetq.jms.bridge.ConnectionFactoryFactory.
