Neven, thx for your reply,
so my question is why when I start my own main without passing -Dcom.sun.management.* properties I can connect to it with jconsole, but I cannot connect with jconsole to tomcat (although it is visible in jconsole) ? both my main, and tomcat, and jconsole are running on the same laptop. regards, Jakub On Sun, Apr 7, 2013 at 3:49 PM, Neven Cvetkovic <neven.cvetko...@gmail.com>wrote: > Jakub, > > "You don't have to" configure Tomcat with above settings to get JMX.
