Re: exposing script variables

[Peter Alfors]

Yep, that will work.  However, I was hoping to mimic what the jsp:useBean tag
does.
I would like to reduce the amount of script code as much as possible.
The jsp:useBean taglib somehow makes the variable accessible to the page
without having to use pageContext.getAttribute().

Does anyone know how this is done??

my temporary solution (which is not real pretty) is for my DefineTag to place
the object into the request, then
use a jsp:useBean tag to retrieve it from the request.

thanks,
    Pete
