Hello again, finally i have a java class that helps me displaying upnp devices , it displays the services of the device too, but no actions found for the services , System.out.println(services.hasActions()) return false, it is weird , any ideas ? package fr.enssat.fgt.upnp.control; import org.teleal.cling.UpnpService; import org.teleal.cling.UpnpServiceImpl; import org.teleal.cling.model.message.header.STAllHeader; import org.teleal.cling.model.meta.Action; import org.teleal.cling.model.meta.LocalDevice; import org.teleal.cling.model.meta.RemoteDevice; import org.teleal.cling.model.meta.Service; import org.teleal.cling.registry.Registry; import org.teleal.cling.registry.RegistryListener; /** * Runs a simple UPnP discovery procedure. * http://4thline.org/projects/cling/core/manual/cling-core-manual.html */ public class Test { public static void main(String[] args) throws Exception { // UPnP discovery is asynchronous, we need a callback RegistryListener listener = new RegistryListener() { public void remoteDeviceDiscoveryStarted(Registry registry, RemoteDevice device) { System.out.println( "Discovery started: " + device.getDisplayString() ); Service[] services = device.getServices(); for(int i=0;i System.out.println(services[i].hasActions()); } } public void remoteDeviceDiscoveryFailed(Registry registry, RemoteDevice device, Exception ex) { System.out.println( "Discovery failed: " + device.getDisplayString() + " => " + ex ); } public void remoteDeviceAdded(Registry registry, RemoteDevice device) { System.out.println( "Remote device available: " + device.getServices().toString() ); } public void remoteDeviceUpdated(Registry registry, RemoteDevice device) { System.out.println( "Remote device updated: " + device.getDisplayString() ); } public void remoteDeviceRemoved(Registry registry, RemoteDevice device) { System.out.println( "Remote device removed: " + device.getDisplayString() ); } public void localDeviceAdded(Registry registry, LocalDevice device) { System.out.println( "Local device added: " + device.getDisplayString() ); } public void localDeviceRemoved(Registry registry, LocalDevice device) { System.out.println( "Local device removed: " + device.getDisplayString() ); } public void beforeShutdown(Registry registry) { System.out.println( "Before shutdown, the registry has devices: " + registry.getDevices().size() ); } public void afterShutdown() { System.out.println("Shutdown of registry complete!"); } }; // This will create necessary network resources for UPnP right away System.out.println("Starting Cling..."); UpnpService upnpService = new UpnpServiceImpl(listener); // Send a search message to all devices and services, they should respond soon upnpService.getControlPoint().search(new STAllHeader()); // Let's wait 10 seconds for them to respond System.out.println("Waiting 10 seconds before shutting down..."); Thread.sleep(10000); // Release all resources and advertise BYEBYE to other UPnP devices System.out.println("Stopping Cling..."); upnpService.shutdown(); } }

Hello, This is my first post here, I'm trying to write a simple java code , that detects upnp devices and display them. could you please give me hand to be able to continue ?!
