So does that mean that what I am trying to do can't be done ... I guess so?
If that is the case, can you suggest what I can do where I need to rewrite
string in the JSP where the string that needs to be rewritten is the result
of a JSTL tag? In my example is the string returned from a database query.
Thanks again,
Stef
