Queue Events to Messaging System

Message-oriented middleware is a common means to enable communication between heterogeneous systems. For example, if a Java system wants to know about events happening in Drupal, this messaging module is one way to provide such information.

The "msgqueue" module integrates Drupal with messaging system like Apache ActiveMQ (a JMS implementation). This module accesses Drupal events by implementing hooks for users, nodes, and comments. The hooks supply events when any insert, update, or delete action takes place for any user, node or comment. An XML message about any such Drupal event is sent to the messaging system. The module formats XML messages using minixml, and puts them into a queue via the Stomp protocol of ActiveMQ.
