Identifying a deadlock in your application using JConsole

It's very simple!!  You need not setup anything for this. JPS and JConsole comes with JDK toolkit.

Step 1:
Got to command prompt and type 'jps' command. This will tell you the currently running java process id's.


7620 org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
7048 Main
5740 Jps

Step 2:
Open jconsole using your application process id, in my case 7048 is my eclipse application process id.

C:\Users\kh1205>jconsole 7048

This will launch jconsole window with various sections.

Step 3:
Navigate to Threads section in jconsole window, and navigate through main thread(ex:main) and worker threads(ex: worker-1, worker-2). In one of these threads, your application is in waiting state.
