With Message Queue 4.2, a publisher can publish messages to multiple topic destinations and a subscriber can consume messages from multiple topic destinations. This capability is achieved by using a topic destination name that includes wildcard characters, representing multiple destinations. Using such symbolic names allows administrators to create additional topic destinations, as needed, consistent with the wildcard naming scheme. Publishers and subscribers automatically publish to and consume from the added destinations. (Wildcard topic subscribers are more common than publishers.)
This feature does not apply to queue destinations.
The format of symbolic topic destination names and examples of their use is described in Supported Topic Destination Names in Sun GlassFish Message Queue 4.4 Administration Guide.
