Java Messaging Service (JMS) and WebLogic

Now that we are familiar with some of the most common ways to connect to a WebLogic Server, let's take a look at one of the features enabled by them, the Java Message Service (JMS) module.

JMS is a Java API that makes the sharing of information between systems or modules possible by sending and receiving messages in an asynchronous way.

WebLogic Server's JMS implementation is compliant with JMS 1.1, and its provider exposes both the message models that are defined by the specification, point-to-point and publish/subscribe, which translate to queue and topic components.
