Howdy,

I just quickly stripped this down, so I don't know if it's totally
bullet-proof...

public class Main {
 public static String getLocation() throws Exception {
   String sName = '/' + Main.class.getName().replace('.', '/') +
".class";
   System.out.println(sName);
   System.out.println(Main.class.getResource(sName));
   String s = Main.class.getResource(sName).getFile();
   int start = s.indexOf('/') + 1, end = s.lastIndexOf('!');
   if (end < 0) {
     s = s.substring(start, s.length() - sName.length());
   } else {
     s = s.substring(start, end);
   }
   return s;
 }
}

It'll return the base-directory containing the Main /class-file/, which
isn't necessarily the location of your executable.  (For instance, if
the executable is a shell that doesn't include the Main class in an
internal archive.)

If you need to find an executable that doesn't contain the classes,
then you've got your work cut out for you.  Either you'd have to go
JNI, or do a scan of all the directories on the PATH, looking for the
executable.  Of course, then you'd have to know in advance what the
executable was called...

Hope this helps,

Walter
