My problem description above could have been a little confusing
(because it's so simple).  The question is really: I am sitting in
a directory named FOO trying to javac a file Bean.java which makes
reference to the class "Foo".  There is a "Foo.java" and "Foo.class"
file sitting in this same directory already.  CLASSPATH includes ".".
Both classes are in the same package FOO.  What else do I need to do?

The problem is presumably unrelated to Tomcat.
(Of course, I still don't realize what the problem is.)

Go up one directory level (i.e. the parent to FOO) and issue the command:

javac.exe -d . FOO.Foo.java

HTH,

Mike
