How do I open a url from an applet?

Question

is it done the same way with HTTPUrlConnection as with an application or is it done in a different way? I'm getting a "ClassCastException"

Answer 1

Now I'm trying to call a CGI script and past things in through the post method... I still get a ClassCastException. This exact same code worked in the applet, once again. here is the code I am using:
               URL url = new URL ("http://address.pl");
               HttpURLConnection cxn = (HttpURLConnection) url.openConnection();
               cxn.setRequestMethod("POST");;
               cxn.setUseCaches(false);
               cxn.setDoOutput(true);
               cxn.setDoInput(true);
               ByteArrayOutputStream bytes = new ByteArrayOutputStream(400);
               PrintWriter writer = new PrintWriter (bytes,true);
               writer.print("hello=world&food=good");
               writer.flush();
               cxn.setRequestProperty("Content-Length",String.valueOf(bytes.size()));
               cxn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
               bytes.writeTo(cxn.getOutputStream());
