How can I force an MBean to be unregistered on undeploy? I use Spring to manage my beans and it exports one of my beans as a MBean when the application is loaded. When I redeploy my application the MBean server throws an InstanceAlreadyExistsException because my MBean from the previous deployment is still alive while Spring is trying to inject a new one.. Anyone knows a work-a-round? cheers, Geir View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3965960#...
