Posting an XML file

This is my first time writing a web-service which invokes a URL. At this time I am trying to invoke a friends url to post xml file content to it. Testing it out, it seemed to work fine as I could invoke a web address such as www.google.com. The address of his I recently received is "http://ift.tt/UNIzUE. When I try and invoke this web address I received a "java.net.unknownhostexception: http://ift.tt/UNIzUE" error. Does anyone have tips on how I could alter my code to paste XML content to this address? Thanks.

public class PostXml {

  public static void main(String[] args) {
        try {
            DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
            InputStream inputStream = new FileInputStream(new File(args[0]));
            org.w3c.dom.Document doc = documentBuilderFactory.newDocumentBuilder().parse(inputStream);
            StringWriter stw = new StringWriter();          
            Transformer serializer = TransformerFactory.newInstance().newTransformer();
            serializer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
            serializer.transform(new DOMSource(doc), new StreamResult(stw));
            String xmldata = (stw.toString());
            //System.out.println(xmldata);
            System.out.println("Post_Request:\n");
            System.out.println(xmldata);

            //Create socket
            String hostname = args[1];
            int port = 80;
            InetAddress  addr = InetAddress.getByName(hostname);
            Socket sock = new Socket(addr, port);

            //Send header
            String path = "/path";
            BufferedWriter  wr = new BufferedWriter(new OutputStreamWriter(sock.getOutputStream(),"UTF-8"));
            // You can use "UTF8" for compatibility with the Microsoft virtual machine.
            wr.write("POST " + path + " HTTP/1.0\r\n");
            wr.write("Host: HostName\r\n");
            wr.write("Content-Length: " + xmldata.length() + "\r\n");
            wr.write("Content-Type: text/xml; charset=\"utf-8\"\r\n");

            wr.write("\r\n");

            wr.write("<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n");
            wr.write("<soap:Envelope xmlns:xsi=\"http://ift.tt/ra1lAU\" xmlns:xsd=\"http://ift.tt/tphNwY\" xmlns:soap=\"http://ift.tt/sVJIaE\">\r\n");
            wr.write("<soap:Body>\r\n");
            wr.write("<CreateNewPR xmlns=\"path\">\r\n");
            wr.write(xmldata + "\r\n");
            wr.write("</CreateNewPR>");
            wr.write("</soap:Body>\r\n");
            wr.write("</soap:Envelope>\r\n");

            //Send data                    
            wr.flush();                     
        System.out.println("\nGet_Response printed in txt file.");

        //Prints response to file
        File file = new File(args[2]);  
        FileOutputStream fis = new FileOutputStream(file);  
        PrintStream out = new PrintStream(fis);  
        System.setOut(out);  

        // Response
        BufferedReader rd = new BufferedReader(new InputStreamReader(sock.getInputStream()));
        String line;
        while((line = rd.readLine()) != null)
            System.out.println(line);
        } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

arg 0 is my xml file, arg 1 is my asmx adress, arg 2 is my output file.txt
