-/**
- * BrowserLauncher is a class that provides one static method, openURL, which
opens the default
- * web browser for the current user of the system to the given URL. It may
support other
- * protocols depending on the system -- mailto, ftp, etc. -- but that has not
been rigorously
- * tested and is not guaranteed to work.
- * <p>
- * Yes, this is platform-specific code, and yes, it may rely on classes on
certain platforms
- * that are not part of the standard JDK. What we're trying to do, though, is
to take something
- * that's frequently desirable but inherently platform-specific -- opening a
default browser --
- * and allow programmers (you, for example) to do so without worrying about
dropping into native
- * code or doing anything else similarly evil.
- * <p>
- * Anyway, this code is completely in Java and will run on all JDK
1.1-compliant systems without
- * modification or a need for additional libraries. All classes that are
required on certain
- * platforms to allow this to run are dynamically loaded at runtime via
reflection and, if not
- * found, will not cause this to do anything other than returning an error
when opening the
- * browser.
- * <p>
- * There are certain system requirements for this class, as it's running
through Runtime.exec(),
- * which is Java's way of making a native system call. Currently, this
requires that a Macintosh
- * have a Finder which supports the GURL event, which is true for Mac OS 8.0
and 8.1 systems that
- * have the Internet Scripting AppleScript dictionary installed in the
Scripting Additions folder
- * in the Extensions folder (which is installed by default as far as I know
under Mac OS 8.0 and
- * 8.1), and for all Mac OS 8.5 and later systems. On Windows, it only runs
under Win32 systems
- * (Windows 95, 98, and NT 4.0, as well as later versions of all). On other
systems, this drops
- * back from the inherently platform-sensitive concept of a default browser
and simply attempts
- * to launch Netscape via a shell command.
- * <p>
- * This code is Copyright 1999-2001 by Eric Albert ([EMAIL PROTECTED]) and may

- * comment from this paragraph through the end of the comment is not removed.

- * that's frequently desirable but inherently platform-specific -- opening a
default browser --
- * and allow programmers (you, for example) to do so without worrying about
dropping into native
- * code or doing anything else similarly evil.
- * <p>
- * Anyway, this code is completely in Java and will run on all JDK
1.1-compliant systems without
- * modification or a need for additional libraries. All classes that are
required on certain
- * platforms to allow this to run are dynamically loaded at runtime via
reflection and, if not
- * found, will not cause this to do anything other than returning an error
when opening the
- * browser.
- * <p>
- * There are certain system requirements for this class, as it's running
through Runtime.exec(),
- * which is Java's way of making a native system call. Currently, this
requires that a Macintosh
- * have a Finder which supports the GURL event, which is true for Mac OS 8.0
and 8.1 systems that
- * have the Internet Scripting AppleScript dictionary installed in the
Scripting Additions folder
- * in the Extensions folder (which is installed by default as far as I know
under Mac OS 8.0 and
- * 8.1), and for all Mac OS 8.5 and later systems. On Windows, it only runs
under Win32 systems
- * (Windows 95, 98, and NT 4.0, as well as later versions of all). On other
systems, this drops
- * back from the inherently platform-sensitive concept of a default browser
and simply attempts
- * to launch Netscape via a shell command.
