JMS providers are message-oriented middleware systems that send and receive JMS messages. WebSphere MQ JMS is an example of a JMS provider.
The RulePoint JMS Source connects to a JMS provider when it reads data from the configured destination - topic or queue. It then publishes the messages that it receives from the configured destination as events to the corresponding topics.
You can also configure a JMS source to read messages from an ultra messaging topic. For more information, see Appendix B: Creating an Ultra Messaging JMS Source.
