Sending XML as the body of a HTTP request

OK. Here goes.

I have to write a standalone Java application that communicates with a server by sending XML requests in the body of a HTML document.

Ther server returns XML.

I am creating my XML using castor and I have looked at using HttpURLConnection to connect to the server.

In the code below the LoginRequestHelp uses castor to generate the XML required for logging in to the system.

The problem with this coode is that it sends the request to the server using a URL parameter not as the body of the HTML request

public void login()

{

LoginRequestHelper lrh = new LoginRequestHelper();

lrh.setPassword(getPassword());

lrh.setUserName(getUserName());

try

{

URL url = new URL(<some url>);

HttpURLConnection c = (HttpURLConnection)url.openConnection();

c.setDoOutput(true);

c.setDoInput(true);

c.setUseCaches(false);

String xml = lrh.getCommandListXML();

String data = URLEncoder.encode("xmlrequest", "UTF-8") + "=" + URLEncoder.encode(xml, "UTF-8");

c.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

OutputStreamWriter wr = new OutputStreamWriter(c.getOutputStream());

System.out.println("sending...\n" + data);

wr.write(data);

wr.flush();

System.out.println("Recieved... ");

// Get the response

BufferedReader rd = new BufferedReader(new InputStreamReader(c.getInputStream()));

String line;

while ((line = rd.readLine()) != null)

{

System.out.println(line);

}

wr.close();

rd.close();

System.out.println(lrh.getCommandListXML());

}

catch (MalformedURLException e)

{

// TODO Auto-generated catch block

e.printStackTrace();

}

catch (IOException e)

{

// TODO Auto-generated catch block

e.printStackTrace();

}

}
