Connecting to internet

When I try to connect to the internet via java i'm getting a

Error in accessing URL: java.net.SocketException: Network is unreachable: connect

I'm trying to read the HTMLCode. The class works perfectly at home but at my university I am facing difficulties.

This is what I'm using:

URL urlAddress =new URL(urlString);

URLConnection connection = urlAddress.openConnection();

inStream =new BufferedReader(new InputStreamReader(connection.getInputStream()));

Can this be fixed? What would I need to use?

Thank you.

You need to contact your uni's system admin. Chances are you are behind a proxy.

Yeah as mentioned your uni will have to unblock your pc (which is relatively simple to do but is a security issue) and you probably wont need to do anything else.

Is it not that your firewall is blocking also? Do you not have to allow javaw.exe access to the Internet?

If you need to use a proxy, your uni will tell you the details and you should be able to set the proxy parameters as explained here: http://java.sun.com/j2se/1.5.0/docs/guide/net/proxies.html
