finding derived classes from base class

[sakcee]

I am trying to find a way to find all the derived classes , given a
parent class, off a source folder or package.
I dont want to load the classes , one way is to have one pass through
code and build a tree with object at root etc

any ideas are appreciated

You can read up on the class file format and load the bytes with nio
and have a look. See http://mindprod.com/jgloss/javaclassformat.html

There are also various libraries for manipulating class file byte
codes.
See http://mindprod.com/jgloss/jasm.html

Ask a specific question.

we have many classes that define static values, we want to load them
by class names and with hierarchies.

I am just looking for a way, any way, of finding all derived classes
given a parent

In the Eclipse IDE, there is a "Type Hierarchy" view. It gives you a
way to navigate the entire inheritance tree.

This is a stronger requirement than you first stated:

There is no way in general to find /all/ derived classes - it's an unbounded
set over time. It should be possible to find all the derived classes in a
specific source folder (or other resource) at a given moment in time, though.

Eclipse (as voorth stated) and Netbeans both have code to do show class
hierarchies, and they are open source.
