JSTL 1.0 and the function library

[Nick Rapagnani]

Because of the difficulty I had integrating Tomcat 5.X with IIS 6, I had to use Tomcat 
4.X instead.  This means no JSP 2.0 and no JSTL 1.1.
 
I had been using the function library for some things, namely trim, replace, indexOf, 
and substring.  I am looking for a replacement library.  The string library from 
Jakarta can do everything except indexOf.  Does anyone know of a good function library 
that I can use?
