How do I determine what running process is using java?

I'm looking at the 'top' output on my linux server. I see that the command 'java' is taking up a lot of memory. How can I use this PID, etc. to see what process actually started up the jvm?

Also, is this process actually the jvm or just some generic command?

Ultimately I just want a way to see more information about this command/process instead of just 'java.'

You could use ps command to get extended information about command which launched process:

ps -fp <pid>

Also you could take information of every java process with ps:

ps -ef | grep java | grep -v grep

You can use the jps and jcmd Java utilities to display running Java processes. Explore their options to find out more about they can provide.
