In Java how to programatically kill process on a specified port in Windows

Question

Basically I am automation an application and prerequisite of my automation is that I am using several 3rd party libs which starts certain processes. At the end of the code execution, I want to close all such processes. The only thing I know is that these process runs on specific port always (for example 61120).

As part of clean up, I want to close the process running on port 61120 programatically in Java.

Answer 1

You could use netstat -a -b to get the executables and the port numbers. After that you can taskkill the executables by name. But i never would use this on a productive machine because it's some kind of ...ahm... dangerous.

Better to start processes by java ( Runtime.getRuntime().execute(...) ) and end them if you do not need them anymore.

Answer 2

Through this you can get the desired processes and port numbers netstat -a -b

Then there is a little API providing the desired functionality to operate with the processes:

Windows Process Library

Answer 3

try netstat -a -o -n Search for the port you need. If the console output is more then re-direct it to some file like: netstat -a -o -n > {drive}:/netlog.log search port in that log file.

taskkill /F /PID
