-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 All,
For some reason, I'm not able to access my Tomcat's JMX beans remotely using jconsole, etc. and so I figured I'd try using the jmxproxy servlet in the manager webapp. I've deployed the manager webapp in the same way I've done in many other installations... I'm fairly sure I haven't screwed it up. I get an exception when calling an open-ended "get" (i.e. it should dump the entire JMX tree): $ curl -v --user jmxproxy:jmxproxy http://localhost/manager/jmxproxy?get * Adding handle: conn: 0x7fd780804000 * Adding handle: send: 0 * Adding handle: recv: 0 * Curl_addHandleToPipeline: length: 1 * - Conn 0 (0x7fd780804000) send_pipe: 1, recv_pipe: 0 * About to connect() to localhost port 80 (#0) * Trying ::1... * Connected to localhost (::1) port 80 (#0) * Server auth using Basic with user 'jmxproxy' > GET /manager/jmxproxy?get HTTP/1.1 Authorization: Basic > am14cHJveHk6am14cHJveHk= User-Agent: curl/7.30.0 Host: localhost > Accept: */* > < HTTP/1.1 200 OK < Date: Wed, 05 Mar 2014 20:57:59 GMT < Cache-Control: private < Expires: Wed, 31 Dec 1969 19:00:00 EST < Content-Type: text/plain;charset=ISO-8859-1 < Content-Length: 3079 < Error - javax.management.RuntimeOperationsException: Exception occurred trying to invoke the getter on the MBean javax.management.RuntimeOperationsException: Exception occurred trying to invoke the getter on the MBean at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.getAttribute(DefaultMBeanServerInterceptor.java:629) at com.sun.jmx.mbeanserver.JmxMBeanServer.getAttribute(JmxMBeanServer.java:678) at org.apache.catalina.manager.JMXProxyServlet.getAttribute(JMXProxyServlet.java:128) at org.apache.catalina.manager.JMXProxyServlet.doGet(JMXProxyServlet.java:107) ... ... ...

I removed my own web application and launched fresh with nothing but the manager and it's still failing.
