029 * BrowserLauncher is a class that provides one static method, openURL, which
030 * opens the default web browser for the current user of the system to the given
031 * URL. It may support other protocols depending on the system -- mailto, ftp,
032 * etc. -- but that has not been rigorously tested and is not guaranteed to
033 * work.
034 * <p>
035 * Yes, this is platform-specific code, and yes, it may rely on classes on
036 * certain platforms that are not part of the standard JDK. What we're trying to
037 * do, though, is to take something that's frequently desirable but inherently
038 * platform-specific -- opening a default browser -- and allow programmers (you,
039 * for example) to do so without worrying about dropping into native code or
040 * doing anything else similarly evil.
041 * <p>
042 * Anyway, this code is completely in Java and will run on all JDK 1.1-compliant
043 * systems without modification or a need for additional libraries. All classes
044 * that are required on certain platforms to allow this to run are dynamically
045 * loaded at runtime via reflection and, if not found, will not cause this to do
046 * anything other than returning an error when opening the browser.
047 * <p>
048 * There are certain system requirements for this class, as it's running through
049 * Runtime.exec(), which is Java's way of making a native system call.
050 * Currently, this requires that a Macintosh have a Finder which supports the
051 * GURL event, which is true for Mac OS 8.0 and 8.1 systems that have the
052 * Internet Scripting AppleScript dictionary installed in the Scripting
053 * Additions folder in the Extensions folder (which is installed by default as
054 * far as I know under Mac OS 8.0 and 8.1), and for all Mac OS 8.5 and later
055 * systems. On Windows, it only runs under Win32 systems (Windows 95, 98, and NT
056 * 4.0, as well as later versions of all). On other systems, this drops back
057 * from the inherently platform-sensitive concept of a default browser and
058 * simply attempts to launch firefox via a shell command.
