Does your company have a firewall that needs a proxy?  That might
be one possibility.

You can find a bit of helpful info on this in the Java FAQ.

The Java FAQ is at   
                        http://www.afu.com

Might be worth bookmarking it, or looking thru it for other info.

Hi,
(perhaps you can help me.)
I'm a beginner and have a similar problem. When I try to open a
connection from the company intranet, I have a FileNotFoundException;
when I use
java -Dhttp.proxyHost=proxyhost
    [-Dhttp.proxyPort=portNumber] download_url
the program simply terminates immediately.

Note. I can use a browser, but not TeleportPro (??).

This is the code:


import java.net.*;
import java.io.*;


public class download_url {
    public static void main(String[] args) throws Exception {

      String base = new String( args[0] ), inputLine;
      URL yahoo = new URL( base );
      BufferedReader in = new BufferedReader(
				new InputStreamReader(
				yahoo.openStream()));
	while ((inputLine = in.readLine()) != null)
		System.out.println( inputLine );
	in.close();
	}
}

Thanks in advance,

Before you buy.

Thanks for the Info
that does seem to be the problem because with further testing we were able
to ascertain that
we can access webpages within the intranet.
But unfortunately still we are unable to access the outside web even using

    // set up to use proxy
    System.getProperties().put("http.proxySet", "true");
    System.getProperties().put("http.proxyHost", proxyHost);
    System.getProperties().put("http.proxyPort", proxyPort);

We are still getting the same exception as before
(java.net.ConnectException: Connection refused: )

if you have any other sugestions as to why this might be so we would be
happy to hear them
