Self-document code -> dependencies

I've been asked to document some legacy code to illustrate the Usages
of some Constant values.  I feel like there should be a way to either
generate the documentation directly from the code or make the code
more self-documenting.  Does anyone have any suggestions?

Basically the constants represent Strings which are passed to a
mainframe to call specific transactions.

Those Consts are referenced in some methods in an internal library,
then that library is consumed by the application.

My document looks like a graph of the relationship of those consts -> methods

First, I thought I could use a Dependency graph to do this for me
(Tried DependencyFinder & Structure 101) but neither of them handled
the straight method to method mapping ; they mostly focused on class
-> class)

The application is in Java 1.4

Thanks
