Comments on: 5 Minute Guide to Spring and JMX http://www.mularien.com/blog/2007/11/09/5-minute-guide-to-spring-and-jmx/ Notes by Peter Mularien on Hibernate, Spring, CSS, Java, etc. Tue, 27 Jul 2010 22:22:44 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: Richard http://www.mularien.com/blog/2007/11/09/5-minute-guide-to-spring-and-jmx/comment-page-1/#comment-23587 Richard Thu, 11 Feb 2010 11:43:37 +0000 http://www.mularien.com/blog/2007/11/09/5-minute-guide-to-spring-and-jmx/#comment-23587 Thanks for this example. I found I needed to do a couple of other things before I could get Tomcat, Eclipse, Spring and JMX to all work together. Anyone having problems getting set up may find this link useful, plus the following page on the same site: http://www.bigsoft.co.uk/blog/index.php/2009/01/19/allow-remote-jmx-management-for-tomcat Thanks for this example.

Got it working on Tomcat6 with a project that already had Spring integrated. Just created a simple bean class, added annotations, and was able to access it with JConsole. However, a couple of things not mentioned above that may be of help: 1) Per Tomcat documentation on JMX added the following to CATALINA_OPTS environment setting: set CATALINA_OPTS="-Dcom.sun.management.jmxremote \ -Dcom.sun.management.jmxremote.port=%my.jmx.port% \ -Dcom.sun.management.jmxremote.ssl=false \ -Dcom.sun.management.jmxremote.authenticate=false" For %my.jmx.port% I set an arbitrary value of 22222. (Pick your own favorite number.) see: http://tomcat.apache.org/tomcat-6.0-doc/monitoring.html 2) When starting JConsole I used the Remote Process (not local) and used the URL: service:jmx:rmi:///jndi/rmi://localhost:22222/jmxrmi Excellent tutorial.

That was the easiest JMX integration ever. Thanks Peter! FYI - This is working with Spring 2.5.6 and JBossAS 5.0 W00t! That was the easiest JMX integration ever. Thanks Peter!

FYI – This is working with Spring 2.5.6 and JBossAS 5.0

Otherwise you may not see your mbeans in jconsole. It seems that if -Dcom.sun.management.jmxremote is not specified, Tomcat will use its own mbean server rather then the platform mbean server.

Nice work. i want to add additional information for those of you running JVM with non US settings(mine is tr(turkey)).
