Debugging JConsole Connection Failed

Question

I have a web application deployed to a remote resin server, and it has JMX turned on.

I can telnet to the remote server i.e

franz@see:/tmp$ telnet &l         


        

Answer 1

Make sure you are running your application with following java properties set

-Dcom.sun.management.jmxremote.port=9005
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false

Try to connect now. If you want to debug this ,you can run the jconsole with following command

jconsole -J-Djava.util.logging.config.file=path_to_logging.properties_for_jconsole

Below is the content of logging.properties file

Logging.properties

handlers = java.util.logging.ConsoleHandler


.level = INFO

java.util.logging.ConsoleHandler.level = FINEST

java.util.logging.ConsoleHandler.formatter = \

java.util.logging.SimpleFormatter

// Use FINER or FINEST for javax.management.remote.level - FINEST is

// very verbose...

javax.management.level = FINEST

javax.management.remote.level = FINER

Once you run jconsole a separate window will pop up displaying logs.
