Simple code sample for beginner

[Anonymous]

Hi,
I discovered Cyberlink for Java while exploring about UPnP AV.
Although the standards mentioned at upnp.org are self-explanatory, the CLink for Java library is not.
There are very few comments/remarks on http://www.cybergarage.org/doxygen/clinkjava/.

I would like to contribute to the project by providing well laid out samples once I get started myself.
Any pointers/links to basic upnp av source code for beginners?

It would be great if someone can attach Java example code for very basic scenario like playing a music/movie(located on a server) file on a TV.

Thanks in anticipation,

To be more specific, I m trying to make the following code work:

public class DlnaTest implements DeviceChangeListener, SearchResponseListener 
{
    private  volatile List<Device> mediaServers;
    private List<Device> mediaRenderers;
    private ControlPoint point;

    public DlnaTest()
    {
        this.mediaServers = new ArrayList<Device>();
        this.mediaRenderers = new ArrayList<Device>();
        point = new ControlPoint(30900,40900); 
        point.start();
        log("point started");
        point.addDeviceChangeListener(this);
        point.search("upnp:rootdevice");
    }

    public void play()
    {
        log("playing starts");
        Device tv = this.mediaRenderers.get(0);
        // ----- unable to figure out the order or actions to be called and parameters to be supplied 
        Action playAction = tv.getAction("SetAVTransportURI");
        playAction.setArgumentValue("CurrentURI", "?????  http://172.16.3.13:30888/__contentStream/5dee2b801c046ee68b8a341eea6b8edd/TVMOBiLi/s0-1481y5z1311799106.mp3");
        playAction.setArgumentValue("InstanceID", "?????");
        playAction.postControlAction();

        playAction = tv.getAction("Play");
        playAction.setArgumentValue("InstanceID", "urn:upnp-org:serviceId:AVTransport");
        playAction.setArgumentValue("Speed", "0");
        playAction.postControlAction();
        log("played");
    }

    @Override
    public void deviceAdded(Device device)
    {
        if(device.getDeviceType().contains("urn:schemas-upnp-org:device:MediaServer:1") )
        {
            log("adding server" +device.getFriendlyName());
            this.mediaServers.add(device);
        }
    }

    @Override
    public void deviceRemoved(Device device) 
    {
        if(device.getDeviceType().contains("urn:schemas-upnp-org:device:MediaServer:1"))
        {
            log("removing server" +device.getFriendlyName());
            this.mediaServers.remove(device);
        }
    }

    @Override
    public void deviceSearchResponseReceived(SSDPPacket arg0) {
    ......  
    }
    public static void main(String[] args) throws InterruptedException, InvalidDescriptionException 
    {

        DlnaTest test = new DlnaTest();
        Device renderer = new Device("C:\\Users\\Paragon\\Desktop\\SamsungMRDesc.xml");
        test.mediaRenderers.add(renderer);
        log("tv added ");
        Thread.sleep(6000);
        test.play();
        test.point.stop();
    }

}

Hi,

I checked your sample code now. But the sample is no good because
the added device is incomplete.

Please check the following users guide 's create user devices normally.

   http://www.cybergarage.org/twiki/bin/view/Main/CyberLinkForJava#Repositories

Please check the following repository about samples for UPnP/AV device too.
