get ResponseCode() and connect()

[IveCal]

Hello, I have getResponseCode and connect() prob here... I want to
connect then get the response code of the remote server. It's been
almost 12 hours but I havent been connected and the server has not
given me a response... I set the time out but it seems not to work..
(Time out is set to 10 seconds.) Here's my code:

System.setProperty( "sun.net.client.defaultReadTimeout",
Integer.toString( 10000 ) );

URL url = new URL(urlString);
URLConnection uc = url.openConnection();
HttpURLConnection hc = ((HttpURLConnection)uc);

hc.setRequestProperty("Accept","image/gif, image/x-xbitmap, image/jpeg,
image/pjpeg, application/x-shockwave-flash, */*");
..
..
..
uc.setRequestProperty("Content-Type","xml/html; charset=utf-8");

hc.setInstanceFollowRedirects(false);
hc.connect();

// -- Check if the response code.
if (HttpURLConnection.HTTP_OK == hc.getResponseCode() ||
HttpURLConnection.HTTP_MOVED_TEMP == hc.getResponseCode() )
{
System.out.println("(Success) Responce Code: "+hc.getResponseCode());
}
else
{
System.out.println("Responce Code: "+hc.getResponseCode());
}

// -- get headers
for (int counter=0; ; counter++)
{
String name = uc.getHeaderFieldKey(counter);
String value = uc.getHeaderField(counter);
System.out.println(name+": "+value);
}

If u think that there's nothing wrong with the connect and
getResponseCode, please help me with the time out thing. Thank you...

// -- get headers
for (int counter=0; ; counter++)
{
String name = uc.getHeaderFieldKey(counter);
String value = uc.getHeaderField(counter);
System.out.println(name+": "+value);
}

This to me looks like an infinite loop. Use uc.getHeaderFields() to get
a map, and iterate over the keys instead of a for loop like you have. I
think your code is running fine, and for the last 12 hours it is
printing null on the log/console.

Hi,

what value of urlString are you using?

Is it definately in the form: "http://<hostname or IP>[:<port>]/<page
to request>"

SORRY.... in addition to the get headers code:
I forgot to place the codition if I found a null...

// -- get headers
for (int counter=0; ; counter++)
{
String name = uc.getHeaderFieldKey(counter);
String value = uc.getHeaderField(counter);
System.out.println(name+": "+value);

/************* I forgot this part here ******************/
if (headerName == null && headerValue == null) {
// No more headers
break;
}
/************* I forgot this part here ******************/
}

My prog has those coditions ALREADY but it still did not word....

Here is the urlString where my prog fails:

It works for me without any changes. Are you behind a proxy?
