ISTR that a mode passed on gnu.emacs.sources to do that. Otherwise,
there's the line-number-mode and column-number-mode that display the
line and column number in the mode line. The point is that it's
rather costly to maintain line numbers while editing a buffer: you
have to renumber all lines every time something's cut, pasted or C-o
or RETURN is typed, etc.
You could use this M-x insert-line-numbers command to insert line
numbers, M-x delete-line-numbers to remove them, M-x renumber-lines to
update them.
And M-x local-set-key RET RET lse-newline RET to get new line numbers
inserted automatically when you type return (actually, not _line_
numbers, but a statement number like in LSE or BASIC where you may
number lines 5 b 5 or 10 by 10.
I don't know if there's a way to maintain an area on the screen
distinct from the buffer contents, but scroll-synchronized with the
buffer, like the "fringe", were we could put the line numbers; it
doesn't seems so...

Look in the list archives (someone just asked last week about the same
thing).

Ok I downloaded:
setnu.el
But what am I supposed to do with it? I am just starting to use emacs.

Put the file in your somewhere in your load-path (to see which
directories are in the load-path, do C-h v load-path RET), then add
the following to your .emacs file:
(require 'setnu)
Now, when you want line numbers do M-x setnu-mode RET

When I do that I get a list of maybe 15 diretories! Should I just put in one
of them?

I could be nice that the linenumbers are visible each time I start emacs, is
that possible?

Yes, basically, any will do.

Not with this mode because it has to be enabled in each buffer, when
you need it. I suggest you bind it to some key:
(global-set-key "\C-cl" 'setnu-mode)
And then you only need to press C-c l to toggle this mode.

Or you can add to to a hook for whichever modes you
want it enabled, i.e. placing in your .emacs file
(add-hook 'java-mode-hook
'(lambda ()
(setnu-mode t))
will turn on line numbers for any buffer that uses java-mode.
