Look at java.net.URLConnection. Create a java.net.URL instance with the URL of the servlet, create an instance of URLConnection and use the various methods of URLConnection to interact with the servlet (i.e. doInput() to POST data or getContent to download). NOTE: An unsigned applet can only establish connections with the same server it was loaded from.

String str;

Hello !!!
You can do this also
----------------
(Code in Applet)
URL helloServletURL = new URL( getCodeBase().toString()+ "HelloServlet" );
URLConnection urlConnection = helloServletURL.openConnection();
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setUseCaches(false);

ObjectOutputStream objOut = new ObjectOutputStream (urlConnection.getOutputStream());
objOut.writeUTF(Id); // pass parameter to servlet
objOut.flush();

ObjectInputStream objIn = new ObjectInputStream(urlConnection.getInputStream());
String state = objIn.readUTF(); // read String from Servlet
----------------
(Code in Servlet)
ObjectInputStream dataInput = new ObjectInputStream(request.getInputStream());
String id = dataInput.readUTF();
ObjectOutputStream dataOutput = new ObjectOutputStream(response.getOutputStream());
dataOutput.writeUTF(status);
dataOutput.flush();
dataInput.close();
dataOutput.close();
--------------------
