与tomcat紧紧相连

我正在尝试创建一个服务来自动发现我本地网络中的upnp设备,在tomcat 7上运行的web应用程序中实现它并使用4thline Cling库。 我收到了这个错误

  

org.fourthline.cling.transport.RouterImpl handleStartFailure   严重:无法初始化网络路由器:org.fourthline.cling.transport.spi.InitializationException:无法在此环境中设置已修改的URLStreamHandlerFactory。无法使用基于HTTPURLConnection的捆绑默认客户端,请参阅手册。

cling's manual中,他们说Cling无法使用Java JDK的HTTPURLConnection进行HTTP客户端操作。他们建议configure network transport

我不太了解该怎么做。有人有类似的问题吗? 你能给我一个例子吗?

感谢。

我使用的代码是:

    public class Example {

    public static void startDiscovery() {

        RegistryListener listener = new RegistryListener() {

            public void remoteDeviceDiscoveryStarted(Registry registry,RemoteDevice device) {


                    String name = device.getDisplayString();
                    String url = device.getDetails().getBaseURL().toString();
                    String friendlyName = device.getDetails().getFriendlyName();


            }

            public void remoteDeviceDiscoveryFailed(Registry registry,RemoteDevice device, Exception ex) {
            }

            public void remoteDeviceAdded(Registry registry, RemoteDevice device) {
            }

            public void remoteDeviceUpdated(Registry registry,RemoteDevice device) {
            }

            public void remoteDeviceRemoved(Registry registry,RemoteDevice device) {
            }

            public void localDeviceAdded(Registry registry, LocalDevice device) {
            }

            public void localDeviceRemoved(Registry registry, LocalDevice device) {
            }

            public void beforeShutdown(Registry registry) {
            }

            public void afterShutdown() {
            }
        };


        try{

            UpnpService upnpService = new UpnpServiceImpl(listener);
            upnpService.getControlPoint().search(new STAllHeader());
            // wait 5 seconds for them to respond
            Thread.sleep(5000);
            upnpService.shutdown();
        }catch(Exception e){
            e.printStackTrace();
        }


    }
}
