I made a currency converter that gets the latest currency rates from yahoo. As long as I run it from the applet viewer it works fine, I can convert any currencies. When I open the html file the applet works but I can't convert any currencies and I can't retrieve any rates.

        Url = "http://finance.yahoo.com/q?s=EURUSD%3DX&ql=1";

        URLPage = new URL(Cur);
        Input = new BufferedReader(new InputStreamReader(URLPage.openStream()));
        while ((inputLine = Input.readLine()) != null) {
          results = results + inputLine;
        }

        Input.close();
        Pattern patternSeeked = Pattern.compile("x\">([0-9.]+)</span>");
        Matcher findMatch = patternSeeked.matcher(results);
        findMatch.find();

The exception I get is java.security.AccessCOntrolException: access denied("java.net.SocketPermission" "finance.yahoo.com:80" "connect,resolve");

Are you getting any exceptions? – Austin Mar 14 '13 at 18:16
No, none. I added a try-catch exception in case it wouldn't connect to yahoo but it's never called. – user2171042 Mar 14 '13 at 18:20
Actually it throws a RuntimeException... – user2171042 Mar 14 '13 at 22:22
Post that stacktrace please. And the relevant lines of code it's referring to. – Austin Mar 15 '13 at 01:01
Only a trusted applet can reach across domains. Is Yahoo permitting you to reuse their data? – Andrew Thompson Mar 16 '13 at 00:59
No, I don't think it is. How do I do it? – user2171042 Mar 18 '13 at 17:10
