How to find the running process by jar

Hi,
I have to do coding for the following scenario,

Suppose when 4 jar files are executed then 4 java.exe will present in task manager. How could I find that which java.exe is executing which jar file.

If anybody have an idea or code please let me know.

Thanks in advance

Hi,
Thanks for your input but it is not the one I wanted. I can get the list of processes and process IDs through Runtime.exec("tasklist"); command. My question is if there are more than one processes with same name(for eg if you open 2 command prompt the task manager will display 2 cmd.exe) how do I identify which process(like cmd.exe) will points to which task(like command prompt).

Thanks in advance
