Use a URLConnection. Something like this:
URL url = new URL("http://www.somewhere.com/servlet/DoSomething");
URLConnection connection = url.openConnection();
((HttpURLConnection)connection).setRequestMethod("POST");
connection.setDoOutput(true);
connection.setDoInput(true); //Only if you expect to read a response...
connection.setUseCaches(false); //Highly recommended...
connection.setRequestProperty("Content-Type", "text/xml");
PrintWriter output = new PrintWriter(new OutputStreamWriter(connection.getOutputStream()));
output.print("<?xml version=\"1.0\" ?>.......");
output.flush();
output.close();
If you set doInput(true) then you'll have to grab an inputStream (connection.getInputStream()) to read the response from the server.
What if in the post method, i want to send 3 parameters, that is cpid, pwd, & msg. msg is in xml format. Is it meant that i hav to do this :
URL url = new URL("http://www.somewhere.com/servlet/DoSomething");
URLConnection connection = url.openConnection();
((HttpURLConnection)connection).setRequestMethod("POST");
connection.setDoOutput(true);
connection.setDoInput(true); //Only if you expect to read a response...
connection.setUseCaches(false); //Highly recommended...
connection.setRequestProperty("Content-Type", "text/xml");
PrintWriter output = new PrintWriter(new OutputStreamWriter(connection.getOutputStream()));
output.print(cpid, pwd, msg);
output.flush();
output.close();
Or any idea?
Okay, I originally misunderstood the request. I thought all you were sending was an XML document (like for an AJAX request osr something).
1. To set Parameters use the setRequestProperty or addRequestProperty. For example:
String msg = "<?xml version=\"1.0\" ?><data><property>property1</property><value>Value1</value><property>Property2</property><value>Value2</value></data>";
connection.setRequestProperty(cpid, "123123123");
connection.setRequestProperty(pwd, "123123123");
connection.setRequestProperty(msg, URLEncoder.encode(msg, "UTF-8"));
2. You don't have to set the Content-type in this instance. You're going to pass everything as String objects and handle on the backend.
3. In your servlet be sure to use String msg = URLDecoder.decode(request.getParameter("msg"), "UTF-8"));
to read your original XML.
HTH.
Make that:
String msg = "<?xml version=\"1.0\" ?><data><property>property1</property><value>Value1</value><property>Property2</property><value>Value2</value></data>";
connection.setRequestProperty("cpid", "123123123");
connection.setRequestProperty("pwd", "123123123");
connection.setRequestProperty("msg", URLEncoder.encode(msg, "UTF-8"));
