Procrun with org.apache.commons.daemon.Daemon

I wrote a Daemon by using the apache commons sample code:

public class LockDaemon implements Daemon {

public void init(DaemonContext context) throws DaemonInitException, Exception {
    LogManager.getLogger().info("initialized with arguments {}", context.getArguments());

public void start() throws Exception {
    LogManager.getLogger().info("Start called");


public void stop() throws Exception {
    LogManager.getLogger().info("Stop called");

public void destroy() {



Unfortunately the example does not mention how to install this class with procrun. Procrun needs a static "Start Method", which I do not have when using the code above.

So which start (and stop) method needs to be set for procrun to make the code above work?

conflict error from g++ compiled files while executing ‘make’ command using apache commons daemon via cygwin

I am just a novice in using cygwin ,apache commons daemon ,jsvc.

Involved in a process of writing a daemon using apache commons daemon and execute via cygwin as a linux daemon. so tried the below instruction given,

Succeeded in ,

sh support/


but, while doing make I am getting conflict errors in g++ compiled files which is in (/usr/include/sys/unistd.h) attached the error below.

used, as a mirror to get g++ gcc compiler , autoconf , GNU make

Got stuck here and not able to generate jsvc executable(looks like a conflict 'lockf'), but no idea whether to correct the header files.

Please help me in resolving the error. Let me know if you need further information regarding the error.

Play framework app as a Windows Service with Apache Commons Daemon

I've been following this link: to get my play framework app installed as a windows service using Apache Commons Daemon (prunsrv.exe).
