WYSIWYG XSL-FO editor java component?

[Fernando Mato Mira]

Hello,

I need a WYSIWYG pure java editor component or a viewer with an API
for mouse click events and a way to reverse map the click position to
the XSL-FO source or tree. It should support PDF (and possibly RTF).
If nothing like this is out there, a pure java transformer library
with the support necessary for building the component would fit the
bill.

Thanks
