From: segalsegal on 19 Jan 2010 15:11 It has been a long time since one could rely on showDocument opening a new browser window because browsers have needed to defend against pop- ups. However, those of us using digitally signed applets were able to use code such as that shown below to use Runtime.exec to do the same thing. Recently, however, we've been getting reports from users of our large applet that for some people using Internet Explorer the code no longer works on Windows XP and Vista. I've tested various configurations of Internet Explorer on XP and Vista and not run into this limitation; i.e. the showInBrowser code below works fine. I'm wondering whether there are settings that would cause this code to fail. Does anyone have any ideas? final static void showInBrowser(URL url) { try { if (microsoftBrowser && windowsOS) Runtime.getRuntime().exec ("iexplore.exe " + url); else if (firefoxBrowser && windowsOS) Runtime.getRuntime().exec ("firefox.exe \"" + url + "\""); else if (macOS) { if (firefoxBrowser) Runtime.getRuntime().exec(new String[] {"open", "-a", "Firefox.app", url.toString()}); else if (safariBrowser) Runtime.getRuntime().exec(new String[] {"open", "-a", "Safari.app", url.toString()}); else Runtime.getRuntime().exec(new String[] {"open", url.toString ()}); } else appletContext.showDocument(url, "_blank"); } catch (Exception e) { System.out.println("Couldn't show in browser: " + e); } }

I'd log the exception (and preferably a stack trace) to a file that can be attached by the end-user to an email. -- RGB
