http Authorization

[BADBOY]

Hi,
I am trying to get an application to post to a servlet, but keep getting
a http 401 code(invalid username or password).
Am almost certain ive got the server, username and password set up right.
Can anyone see anything wrong with code

private void doLogin(String name,String pass){
try{
URL url = new URL("http://127.0.0.1/servlet/jl.CheckLogin");
String
request="name="+URLEncoder.encode(name,"UTF-8")+"&pass="+URLEncoder.encode(p
ass,"UTF-8")+"\r\n";
URLConnection c = url.openConnection();
c.setDoOutput(true);
c.setDoInput(true);
c.setUseCaches(false);
c.setRequestProperty("Authorization:","Basic
"+authName+":"+authPass);

c.setRequestProperty("Content-type","application/x-www-form-urlencoded");
c.setRequestProperty("Content-Length",""+request.length());
DataOutputStream out = new
DataOutputStream(c.getOutputStream());
out.writeBytes(request);
out.flush();
out.close();

// DataInputStream in =new DataInputStream(c.getInputStream());
// Handle data from servlet through in.

}catch(MalformedURLException murle){
statusLabel.setText(String.valueOf(murle));}
catch(IOException ioe){ statusLabel.setText(String.valueOf(ioe));}
}

c.setRequestProperty("Authorization:","Basic
"+authName+":"+authPass);

You have to Base64-encode the "userassword"-part of the authorization
header.

Anyway, the right way to do this would be to use a java.net.Authenticator.
