Using a message bus to de-couple disparate systems Messaging Concepts 16 can allow systems and some emerging standards in this space. Let's take a brief look at these: Java Message Service (JMS) JMS is part of Oracle's Java EE specification. It's a Java API that encapsulates both message using JCA would be illegal according to the Java EE specification. The application server's JCA service provides extra functionality such as connection pooling and automatic transaction enlistment, which
