Depending on what your package declaration is, you may need to play
with your classpath a little bit.

So, let's consider two classes that are part of the fictional
math.topology.spaces package.  Call one HausdorffSpace and the other
TopologicalSpace.  HausdorffSpace extends TopologicalSpace.  These
files live in ~/top-axioms/src/math/topology/spaces/.

If you let your current working directory be
~/top-axioms/src/math/topology/spaces/ and run javac against
HausdorffSpace.java, it should bark about not being able to find the
parent class.  There're two easy solutions here:

1) You can pass -cp ~/top-axioms/src/ as an option to javac.
2) You can run javac from ~/top-axioms/src/

I would highly advise throwing together the appropriate things to make
ant work to evade this down the line though.

Hope this helps,
