Last week I had my first US patent issued: #7218708. The patent describes the use of the J2EE Connector Architecture to integrate a Java Message Service provider with an application server. This is something that is actually very easy to do with JCA 1.5 given the restriction of one JMS session per connection introduced by J2EE 1.4. However this patent describes a mechanism to use JCA twice (once at the connection level and once at the session level) that doesn’t require this restriction. This was first used in WebSphere Application Server V5 and continues to be used for the WebSphere MQ and generic JMS provider support today.
