Hi, Are there RabbitMq client libraries for jdk1.4 or any workaround for integration with jdk1.4 based java applications? I think oldest of client library that I saw on this URL: http://www.rabbitmq.com/releases/rabbitmq-java-client/ is v1.4.0 which is built using jdk1.5. Let me know if need to look some place else. Thanks, Rishi
