JConsole can't find process

Question

I tried to run JConsole to analyze the memory used by a running process, but JConsole doesn't show me processes even though I am absolutely sure that one is running (in addition to that it should show JConsole in the process list as well but it doesn't).

Does anyone have an idea why it doesn't show any processes?

Cheers

at window prompt, run echo %TMP%, it will give you default temp dir. Go to that directory and find directory named hsperfdata_user where user is your login. This is directory to store your process id. Any new process you created such as java application will have a new file named by process id. Jconsole will pick up the process ids from this directory. If you cannot create a file in this directory, that means you need change permission to allow write. Once done that, start a new java application to see if new process id file is in the dir. Once confirmed, start jconsole
