    @Override
    public void writeTo(OutputStream out) throws IOException {
        try {
            TransformerFactory transformerFactory = TransformerFactory.newInstance();
            Transformer transformer = transformerFactory.newTransformer();
            transformer.setOutputProperty(OutputKeys.INDENT, "yes");
            Source source = new StreamSource(new StringReader(content));
            Result result = new StreamResult(out);
            transformer.transform(source, result);
        } catch (TransformerException e) {
            throw new IOException(e.getMessage(), e);
        }
    }
}

43. Using HTTP Payloads

import javax.xml.ws.BindingProvider;

public class UsingHttpPayloads {

    public static void main(String[] args) {
        BindingProvider bindingProvider = (BindingProvider) port;
        Map<String, Object> requestContext = bindingProvider.getRequestContext();
        requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "http://example.com/myService");
        requestContext.put(BindingProvider.HTTP_REQUEST_METHOD_PROPERTY, "POST");
        requestContext.put(BindingProvider.PAYLOAD_PROPERTY, "mypayload");
        bindingProvider.invoke(new Object[]{});
    }
}

44. Using HTTP Attachments

import javax.xml.ws.http.HTTPBinding;

public class UsingHttpAttachments {

    public static void main(String[] args) {
        HTTPBinding binding = (HTTPBinding) port.getBinding();
        binding.setAttachments(true);
    }
}

45. Using HTTP Resources

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/myResource")
public class MyResource {
    
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String getSomething() {
        return "Hello world";
    }
}

46. Using HTTP WebSocket

import javax.websocket.ClientEndpoint;
import javax.websocket.CloseReason;
import javax.websocket.OnClose;
import javax.websocket.OnError;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;

@ClientEndpoint
public class MyWebSocketClient {

    @OnOpen
    public void onOpen(Session session) {
        // Connect to the websocket server
    }

    @OnClose
    public void onClose(Session session, CloseReason reason) {
        // WebSocket connection closed
    }

    @OnMessage
    public void onMessage(String message, Session session) {
        // Receive message from the websocket server
    }

    @OnError
    public void onError(Throwable t) {
        // Error occurred while connecting to the websocket server
    }
}

47. Using HTTP Server Sent Events (SSE)

import javax.servlet.http.HttpServletResponse;

public class MySseServlet {

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
        response.setContentType("text/event-stream");
        response.setCharacterEncoding("UTF-8");

        PrintWriter writer = response.getWriter();
        writer.write("data: Hello world!\n");
        writer.write("\n");
        writer.flush();
    }
}

48. Using HTTP Server Push (HTTP/2)

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/myResource")
public class MyResource {

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String getSomething() {
        // Push a new response to the client
        return "Hello world";
    }
}

49. Using HTTP Byte Streams

import javax.xml.ws.http.HTTPBinding;

public class UsingHttpByteStreams {

    public static void main(String[] args) {
        HTTPBinding binding = (HTTPBinding) port.getBinding();
        binding.setChunkedStreamingMode(true);
        InputStream stream = binding.getHTTPResponseStream();
        byte[] buffer = new byte[1024];
        int bytesRead;
        while ((bytesRead = stream.read(buffer)) != -1) {
            // Process the bytes in the buffer
        }
    }
}

50. Using HTTP Chunk Sizes

import javax.xml.ws.http.HTTPBinding;

public class UsingHttpChunkSizes {

    public static void main(String[] args) {
        HTTPBinding binding = (HTTPBinding) port.getBinding();
        binding.setChunkStreamSizes(1024);
    }
}
