Not sure I get it. Are you making a new expression language or just
evaluating Velocity expressions?
The introspector is what resolves objects and methods in Velocity.

Velocity.evaluate() renders textual output to a Writer. For the
expression language to work, I need to resolve objects. I can't find
anything in the javadocs that might give me a hook.
Any suggestions?
I know, I need to wade through the code, but a few starting pointers
would help.
Thanks,
Jeff
