Debugging JConsole Connection Failed

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

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 file

handlers = java.util.logging.ConsoleHandler

.level = INFO

java.util.logging.ConsoleHandler.level = FINEST

java.util.logging.ConsoleHandler.formatter = \


// Use FINER or FINEST for - FINEST is

// very verbose... = FINEST = FINER

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

if you run jconsole -debug it gives you more diagnostic info on the failure. See the Daniel Fuchs blog entry "Troubleshooting connection problems in JConsole".

I did this and it showed me I was using 32 bit jconsole the target process was started with a different (64 bit) jvm, so apparently this isn't allowed and it was thus failing.

This finally made it work for me : Giving this extra option: -Djava.rmi.server.hostname=<ip addres where jvm is running

So all the vm arguments used to open jconsole from a remote machine, the jvm on the remote machine must be started with<port> -Djava.rmi.server.hostname=<ip address>

The entire process is listed here
