Answer 1

Assuming that what you are really after is a way to terminate the correct the correct process later on, then an alternative solution is this:

Run ps -ef | grep java and you should get a listing that looks something like this:

 mruser    7518  7505  4 11:37 pts/3    00:00:00 /usr/bin/java -classpath MRD3030_Linked.jar peralex.MyApp

Then pkill -f peralex.MyApp will kill the correct process.

I needed a workaround for this in windows to enable me to stop particular java processes. I've settled on using a .bat file to run the different .jar files, with the first line of the .bat file being TITLE "Name to give the cmd window", then when I look through the different cmd windows I can see which on is the one I want to stop and Ctrl-C via that cmd window.

Not all flavors of exec support the -a flag. If yours doesn't, the argv0 program does something similar.

Answer 4

This is specific to Windows.
I was facing the same issue where I have to kill the specific java program using taskkill. When I run the java program, tasklist was showing the same program with Image name set as java.exe. But killing it using taskkill /F java.exe will stop all other java applications other than intended one which is not required.

So I run the same java program using:

start "MyProgramName" java java-program..

Here start command will open a new window and run the java program with window's title set to MyProgramName.

Now to kil this java-program use the following taskkill command:

taskkill /fi "MyProgramName"

Your Java program will be killed only. Rest will be unaffected.
