I have to migrate the application which is supported by Jboss4.2.3 to some latest Jboss that would support Hot deployment feature. I have already converted the ear project to war for this removed ejb and added spring for this , and that is successfully deployed on Jboss4.2.3. But Jboss4.2.3 does not support hot deployment feature. So which Jboss server would be feasible to migrate so to achieve Hot-Deployment. Can you please suggest on this .
