Message-driven beans can process JMS messages or other kinds of messages."

Getting Started with Java Management Extensions (JMX): Developing Management and Monitoring Solutions: "The JMX technology enables Java developers to encapsulate resources as Java objects and expose them as management resources in a distributed environment. The JMX specification lists the following benefits to using it to build a management infrastructure:

Manages Java applications and services without heavy investment: JMX architecture relies on a core managed object server that acts as a management agent and can run on most Java-enabled devices. Java applications can be managed with little impact on their design."
