Use this task to configure a JMS resources for publish/subscribe
messaging.
For an application to use publish/subscribe messaging with JMS
topics, you need to configure the following JMS resources. These JMS resources
depend on the corresponding configuration of service integration resources,
including a service integration bus and topicspace. For more information about defining these resources,
see the related tasks.
- A JMS connection factory
You should use the connection
factory type that matches the JMS level and domain pattern in which an application
is developed. For example, use a domain-independent JMS connection factory
for a JMS application developed to use JMS 1.1 domain-independent interfaces,
and use a JMS topic connection factory for a JMS application developed to
use domain-specific topic interfaces.
If durable subscriptions are to
be used by the application, then you need to set the durable
subscription properties on the connection factory.
- A JMS topic
A JMS topic is an administrative
object that encapsulates the name of a topic and a topic space on a service integration bus. Applications can obtain the JMS topic by looking its name up in
the JNDI namespace.
- Service integration resources For each JMS topic, you
need to define a bus destination as a topic space on a service integration bus, and assign the JMS topic to a topic name within that topic space.
