Default messaging
Use these topics to learn about using the default messaging provider to support the use of the JMS by enterprise applications deployed on WAS.
The default messaging provider is installed and runs as part of WAS.
The default messaging provider supports JMS 1.1 domain-independent interfaces (sometimes referred to as "unified" or "common" interfaces). This enables applications to use the same common interfaces for both point-to-point and publish/subscribe messaging. This also enables both point-to-point and publish/subscribe messaging within the same transaction. With JMS 1.1, this approach is recommended for new applications. The domain-specific interfaces are supported for backwards compatibility as described in section 1.5 of the JMS 1.1 specification.
The default messaging provider is based on service integration technologies. We can use the WAS administrative console to configure JMS resources:
- A JCA activation specification to enable a message-driven bean to communicate with the default messaging provider.
- A JMS connection factory to connect to a service integration bus
- A JMS queue or topic assigned to a bus destination on the bus.
Such JMS queues and topics are available, over a long period of time, to all applications with access to the bus destination.
