WAS v8.5 > TroubleshootTroubleshooting Messaging resources
The use of asynchronous messaging resources for enterprise applications with WebSphere Application Server.
WAS supports asynchronous messaging based on the JMS and the JCA specifications, which provide a common way for Java programs (clients and Java EE applications) to create, send, receive, and read asynchronous requests, as messages.
JMS support enables applications to exchange messages asynchronously with other JMS clients using JMS destinations (queues or topics). Some messaging providers also allow WAS applications to use JMS support to exchange messages asynchronously with non-JMS applications; for example, WAS applications often need to exchange messages with WebSphere MQ applications. Applications can explicitly poll for messages from JMS destinations, or they can use message-driven beans to automatically retrieve messages from JMS destinations without explicitly polling for messages.
WAS supports the following messaging providers:
- The default messaging provider (which uses service integration as the provider).
- The WebSphere MQ messaging provider (which uses your WebSphere MQ system as the provider).
- Third-party messaging providers that implement either a JCA v1.5 resource adapter or the ASF component of the JMS v1.0.2 specification.
