Check application version on application startup if new update found exit application and open browser that directs to download link..

        if(checkVersion()){
            Browser.getDefaultSession().displayPage("http://download.com/file...");
            System.exit(0);
        }

checkVersion() {
    // get version information from server
    // compare with working copy
    if (update)
        return true;
    else
        return false;
}
