Ok, after all the possibilities I have chosen to work with "Java Monitoring and Management" Overview is here That allows you to control one application from another one in relatively easy way. You can call the controlling application from a script to stop controlled application gracefully before killing it. Here is the simplified code: Controlled application: run it with the folowing VM parameters: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9999 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false //ThreadMonitorMBean.java public interface ThreadMonitorMBean { String getName(); void start(); void stop(); boolean isRunning(); } // ThreadMonitor.java public class ThreadMonitor implements ThreadMonitorMBean { private Thread m_thrd = null; public ThreadMonitor(Thread thrd) { m_thrd = thrd; } @Override public String getName() { return "JMX Controlled App"; } @Override public void start() { // TODO: start application here System.out.println("remote start called"); } @Override public void stop() { // TODO: stop application here System.out.println("remote stop called"); m_thrd.interrupt(); } public boolean isRunning() { return Thread.currentThread().isAlive(); } public static void main(String[] args) { try { System.out.println("JMX started"); ThreadMonitorMBean monitor = new ThreadMonitor(Thread.currentThread()); MBeanServer server = ManagementFactory.getPlatformMBeanServer(); ObjectName name = new ObjectName("com.example:type=ThreadMonitor"); server.registerMBean(monitor, name); while(!Thread.interrupted()) { // loop until interrupted System.out.println("."); try { Thread.sleep(1000); } catch(InterruptedException ex) { Thread.currentThread().interrupt(); } } } catch(Exception e) { e.printStackTrace(); } finally { // TODO: some final clean up could be here also System.out.println("JMX stopped"); } } } Controlling application: run it with the stop or start as the command line argument public class ThreadMonitorConsole { public static void main(String[] args) { try { // connecting to JMX System.out.println("Connect to JMX service."); JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://:9999/jmxrmi"); JMXConnector jmxc = JMXConnectorFactory.connect(url, null); MBeanServerConnection mbsc = jmxc.getMBeanServerConnection(); // Construct proxy for the the MBean object ObjectName mbeanName = new ObjectName("com.example:type=ThreadMonitor"); ThreadMonitorMBean mbeanProxy = JMX.newMBeanProxy(mbsc, mbeanName, ThreadMonitorMBean.class, true); System.out.println("Connected to: "+mbeanProxy.getName()+", the app is "+(mbeanProxy.isRunning() ? "" : "not ")+"running"); // parse command line arguments if(args[0].equalsIgnoreCase("start")) { System.out.println("Invoke \"start\" method"); mbeanProxy.start(); } else if(args[0].equalsIgnoreCase("stop")) { System.out.println("Invoke \"stop\" method"); mbeanProxy.stop(); } // clean up and exit jmxc.close(); System.out.println("Done."); } catch(Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } } That's it. :-)
