Overview
This tab defines multicast configuration attributes for a topic destination. After defining a JMS server, you can configure its topics. You can configure one or more topics for each JMS server.
Note: You configure destinations explicitly or by configuring a JMS template that can be used to define multiple destinations with similar attribute settings, as described in JMS Template Tasks.
