Subject: retrieving URL's from servlet through firewall ?
> Hey all,
>
> I'm trying to retrieve a URL from my servlet using the URL class
> and then making a inputreader from the URL.openstream, etc.
>
> The problem I have is how to do this through the firewall and the proxy
for
> that.
> I've got no idea so, please, any help is appreciated.
>
> Even though I 'open' my account with the firewall so that it doesn't ask
me
> the user name and passwd (like within a browser) I still get an
IOException
> using the following code:
> -----------------
> try
> {
> search_url = new URL(Query);
> File outFile = new File(fileName);
> PrintWriter outStream = new PrintWriter(new FileWriter(outFile));
> BufferedReader inStream = new BufferedReader(new
> InputStreamReader(search_url.openStream()));
> String line;
> while ((line = inStream.readLine())!= null)
> {
> outStream.println(line);
> }
> inStream.close();
> outStream.close();
> } catch (MalformedURLException ex)
> {
> dbWin.println(col,"Error in doSearch: MalformedURLException occured.");
> } catch (NoRouteToHostException ex)
> {
> dbWin.println(col,"Error in doSearch: NoRouteToHostException
occurred.");
> } catch (IOException ex)
> {
> dbWin.println(col,"Error in doSearch: IOException occurred.");
> }
> ------------

> Sorry for the long code excerpt.

> Thanx,
