I am using glassfish 3.1 as my application server and I have enabled JMX by adding the <jmxConfigurator/> tag in the logback.xml. I am able to view the logback classic mbeans on jconsole but invoking operations like getLoggerLevel fails with an error - "Problem invoking getLoggerLevel : java.lang.IllegalStateException: WEB9031: WebappClassLoader unable to load resource[java.lang.Object], because it has not been started or was always stop...." Accessing the "LoggerList" attribute also does not give any output. Statuses attributes shows the status messages though. Is there anything I am missing in terms of configuration? -- View this message in context: http://old.nabble.com/Logback-JMX-Operations-and-Attributes-tp31423995p31423...
