Nice intro from the Rabbit team: http://www.rabbitmq.com/tutorial-one-java.html
I finally finished building an enterprise messaging system using Spring, JMS, and ActiveMQ integrated with Flex Messaging from Livecycle Data Services and a clients in both Flex and Java. The Flex-Java(Spring) integration is handled by Anvil for this project.
I plan to re-configure this in a simplified app using BlazeDS, Spring BlazeDS Integration with Spring, ActiveMQ, Flex, JMS and putting the source code here for a test drive in Tomcat, unless SpringSource beats me to the punch
I probably won’t finish this for at least a month though since I’m still tuning the Spring/ActiveMQ configuration for enterprise use cases.
