Java Programming

hello everybody, i'm using this to read a xml from internet:

       URL url;
            HttpURLConnection urlcon;
            url = new URL (urlString);
            System.out.print("Connecting ....\t");
            urlcon = (HttpURLConnection)url.openConnection();
            if(!urlcon.getResponseMessage().equals("OK"))
                return -1;
            System.out.println("Done!");

it gives me:

java.net.SocketException: Connection reset
at java.net.SocketInputStream.read(Unknown Source)
at java.io.BufferedInputStream.fill(Unknown Source)

at java.net.HttpURLConnection.getResponseCode(Unknown Source)
at java.net.HttpURLConnection.getResponseMessage(Unknown Source)

when i do urlcon.getResponseMessage()....

Any ideas why this happens?

PS: when i try the same URL in a browser, it opens the file fine .....
