Hi, Anton. By the way, eclipse.newcomer is a better newsgroup for asking
questions about the basics of Eclipse.
In this case, I think your problem is that you don't actually have a main
routine. I know it looks like you do, but you don't :-) The "real" main()
routine needs to have a String[] parameter, like this:
static void main(String[] args) { ... }
When you create a new class in Eclipse, there's a checkbox to tell it to add
the main() routine automatically, and that way you won't have to worry about
getting it right.
Add a String[] param to your main routine and I think you'll be off and
running again.

Trust me, you won't be the last person to make that mistake :-)

Of course I know main method's signature. The problem is that I often deal with C++, where main usually has no arguments. Anyway, thanks for your reply.
