Detect if a process is running using WMIC Tag(s): Misc Prog HowTo Java Environment
WMIC is a powerful Windows utility. You can use to know if a particular process is running or not.
This example detects if a Tomcat instance (can be anything, ex: Apache or Excel) is running from a batch file.
@echo off wmic process list brief | find /i "tomcat.exe" set result=%ERRORLEVEL% if "%result%"=="1" echo "not running" if "%result%"=="0" echo "running"
For Java code :
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
public class WindowsUtils {
private WindowsUtils() {}
public static boolean isProcessRunning(String processName) throws IOException {
InputStream is = null;
InputStreamReader isr = null;
BufferedReader br = null;
List<String> command = new ArrayList<String>();
command.add("WMIC");
command.add("process");
command.add("list");
command.add("brief");
try {
ProcessBuilder builder = new ProcessBuilder(command);
Process process = builder.start();
is = process.getInputStream();
isr = new InputStreamReader(is);
br = new BufferedReader(isr);
String line;
processName = processName.toUpperCase();
while ((line = br.readLine()) != null) {
if (line.toUpperCase().indexOf(processName) > -1) return true;
}
return false;
}
finally {
if (br != null) br.close();
if (isr != null) isr.close();
if (is != null) is.close();
}
}
public static void main(String[] args) throws IOException {
System.out.println(WindowsUtils2.isProcessRunning("excel.exe"));
}
