You should mark this as a "pure" package:

package JB is
   pragma Pure;
end;

The mapping of file names to compilation units is compiler-specific.  If
you're using GNAT, for example, then this file would need to be named
jb-a.ads.

(However, if you're using GNAT, it should have given you a warning when you
tried to compile the spec.)

In GNAT, this needs to be named jb-a.adb.

The latter.
