Answer 1

Here is the code for a method that fails gracefully.

Note that the string can be the location of an html file.

/**
* If possible this method opens the default browser to the specified web page.
* If not it notifies the user of webpage's url so that they may access it
* manually.
* 
* @param url
*            - this can be in the form of a web address (http://www.mywebsite.com)
*            or a path to an html file or SVG image file e.t.c 
*/
public static void openInBrowser(String url)
{
    try
        {
            URI uri = new URL(url).toURI();
            Desktop desktop = Desktop.isDesktopSupported() ? Desktop.getDesktop() : null;
            if (desktop != null && desktop.isSupported(Desktop.Action.BROWSE))
                desktop.browse(uri);
        }
    catch (Exception e)
        {
            /*
             *  I know this is bad practice 
             *  but we don't want to do anything clever for a specific error
             */
            e.printStackTrace();

            // Copy URL to the clipboard so the user can paste it into their browser
            StringSelection stringSelection = new StringSelection(url);
            Clipboard clpbrd = Toolkit.getDefaultToolkit().getSystemClipboard();
            clpbrd.setContents(stringSelection, null);
            // Notify the user of the failure
            WindowTools.informationWindow("This program just tried to open a webpage." + "\n"
                + "The URL has been copied to your clipboard, simply paste into your browser to access.",
                    "Webpage: " + url);
        }
}

Answer 2

URI oURL = new URI(url);
Desktop.getDesktop().browse(oURL);

Apart from that, make sure that file is already opened in your desired browser. Check the icon on the file, If it is showing like a text file, you might have already opened with Text file. So change the default program to the desired program.

Answer 3

I would prefer to use default browser

File htmlFile = new File(url);
Desktop.getDesktop().browse(htmlFile.toURI());
