The problem is, that application clients have no means to control their life cycle. They cannot be stopped and undeployed. What behaviour would you expect? 1. the application client is deployed 2. the "java:comp/env" is set up 3. the main method (manifest) is called and thus the application is started. The main method will most probably return immediately. Now you don't have any control over the application anymore. You could run the main method once more but you cannot stop it. Then somebody is removing the application-client.jar, what would you expect to happen now? A possible solution is a blocking main method, that is waiting for a notify on the mainclass as the signal to stop. What you need would be kind of a mix of a service and an application-client. something, that has a life cycle and the configurability of an application-client. However, on the client the situation is different. The JBoss kernel would have a life span equal to that of the application.
