You don't have to use a JMX connection, even: you can just query the local JMX server for the bean object and interrogate it. Lance, look at the source code to the JMXProxyServlet and you can see how to fetch JMX beans from the server. Then, just write some code to do the same thing for the bean you're looking for and grab the data you want. Or, you could just use the JMX proxy servlet directly to fetch the data you want. Why do you want this information from /inside/ the application, rather than outside of it? - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJT2nzeAAoJEBzwKT+lPKRYZqkP/0y/m6XFlb689l64rHzmH9ia pVjtPkoTGTNFNEcYbYEM1yK2n56Ty9kbzP0svhNRJPfsBghvhXOi/qG7IQ6cxTq0 skFQ+ybCXCFuUviaTUdrzYbrB+AkKRT3K9gnjOHdRetlLGCJffmDPVHiUyQekAMF s4jHBaEJ466rrScfQtW8hMEA+S8ra9gRDkYV2h9jjwuXohqAIc6qgnDsUBlzQzgp JceP4PjuaDr1KAONGY+tJ7fLxHwf2GLs0D7urfIRPH9dlxk3pv2O0JzzXpk2pXsX yxm02JSQGX1jk1EbNNqzB8+eUf7coMWseRfbRGuvB2GgB4zWGeq9qFwgsl83FT1k RpSUf6XWrXduVw9FHev5Usus/riqP71lZjZAg1EgM/DJXdXmcfIOElQrOCI0nTra WMuB+p1XSLPf57RffsjkMy4SyqQjcryK4Z6pjYHiezYe//7hCqpMQeFhx4tIRh6g jWSsO0ayGmurmzX0LjteYSR9ru6tFlxqQ+2taGR0ZgdCmiVwfc4CTLj7orgRojJg XsD5K0jnyIXbvXdgdD0qfWs4eJIDBgquRX+A97qUAtoLOqBy/s9hv/OHIYfqlbbW KOxSm2YlJ/TYm+pZOKJlHYh7W1+tErq7C+2AqqD78bytgetCYEHihYmIGRP0HpiP zr2jw9wnMaGJcpUTPwN9 =2Vqm -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
