Components used in a JMS configuration
When an application is written to access an asynchronous messaging system through JMS, it is typically in one of two ways:
- Generic JMS usage
Using the JMS API to send and receive messages. The application relies on WAS to locate the relevant messaging system and to handle the connections to it. What the application does with sending and receiving the messages is entirely down to the application developer within the bounds of the JMS API.
- JMS and Message-Driven Beans
The application relies on WAS to monitor the underlying messaging system and pass any new messages to an instance of a purpose built MDB that will handle the message.
