Open Message Queue (OpenMQ)is an open source Message Oriented Middleware project by Sun Microsystems that implements the Java Message Service 1.1 API (JMS). The commercial version is called Sun Java System Message Queue. In addition to support for the JMS api, OpenMQ provides additional enterprise features including clustering for scalability and High Availability, a C API, and a full JMX administration API. It also includes an implementation of the Java EE Connector Architecture (JCA) called the JMSRA, that allows OpenMQ to be used by a J2EE compliant Application Server. OpenMQ is the default JMS provider integrated into glassfish.
