Systems and/or methods for policy-based jms broker clustering

The example embodiments disclosed herein relate to application integration techniques and, more particularly, to application integration techniques built around the publish-and-subscribe model (or one of its variants). In certain example embodiments, a publishing application, and first and second broker clusters are provided. Each broker cluster comprises a plurality of brokers, and each broker is configured to relay messages from the publishing application to at least one subscribing application. A composite cluster connection is associated with the publishing application, and cluster connections are associated with the composite cluster connection. The message generated by the publishing application is sent to the broker cluster in accordance with a user-defined composite policy. The message is routed from the composite cluster connection to at least one cluster connection based on a first policy layer. The messaging is routed from the at least one cluster to at least one broker based on a second policy lay
