Run ProcessBuilder under another user in linux

Question

I need to run another java app under Debian system but I need to run it under another user. The main java app is running under root. Now I am using this to start another java app but I need to run all this as another user, is it somehow possible ?

        ProcessBuilder processBuilder = new ProcessBuilder(new String[]{"java", "-Xms256M", "-Xmx" +    DataManager.getMaxMemory(server) + "M", "-XX:MaxPermSize=256M", "-jar", "/home/apps/jar/" + DataManager.getJar(server), "nogui"});
        File folder = new File("/home/apps/servers/" + server + "/");
        processBuilder.directory(folder);
        Process p = processBuilder.start();

Thanks.

Solved:

ProcessBuilder processBuilder = new ProcessBuilder(new String[] { "su", "-
s", "/bin/sh", "myuser", "-c", "java -jar myjar.jar" });,
Process p = processBuilder.start();

This code will start "myjar.jar" application under the user "myuser". You can confirm that using the unix command "top" and see the entered user process list.

This solution is system-dependent. – Jezor Jul 18 '20 at 13:40
