Getting Apache documentroot from within a TaglibHelper-based Taglib

[James Lavery]

Hi all,
In my Taglib, which I've written using TaglibHelper, I need to create
some temporary files under my documentroot, and then reference them in
my final HTML.  
 
In order to do this elegantly, I need to be able to get the location of
documentroot at run time.  Can I get this through TaglibHelper, or do I
need use a different mechanism?
 
Thanks,
 
James
