My own problem with gcj

[Brent Fulgham]

Title: RE: My own problem with gcj





Isn't this just the fact that your class has
no main() routine for an entry point?


Java from Sun's JDK would choke on this, too,
because all you have here is a class.  There
is no entry point.


Try adding a main() to your program.
