Does anybody know when to apply the DefaultCachTimeout = 0 to flush the user credentials, and when to use the following code to flush? thanks, ObjectName jaasMgr = new ObjectName("jboss.security:service=JaasSecurityManager"); Object[] params = {domain}; String[] signature = {"java.lang.String"}; MBeanServer server = (MBeanServer) MBeanServerFactory.findMBeanServer(null).get(0); server.invoke(jaasMgr, "flushAuthenticationCache", params, signature); View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4120649#...
