Function Re-use in JSTL
Hey experts,
Is there a way to make a user-defined function in JSTL in order to do something such as percentage computation or in order not to repeat a block of JSTL code; or is the only way to do that is to write this function in the java bean or object class, and then call it from JSTL?? any help on the best method to do this??

I think that the best way would be to create a custom tag (similar to JSTL) by your own.

Is there an easier way, or how difficult is creating tags of my own?

How do I know which JSP version this project is on & which JSTL version I am using?
(I am confused a bit also about the differences between JSTL 1.0,1.1 & 1.2)

>& which JSTL version I am using?
Which directive are you using ?
<%@taglib uri="http://java.sun.com/jstl/core" prefix="c"%> // this is for JSTL 1.0
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> this is for JSTL 1.1

It turns out that I am using JSTL 1.0 with JSP 2.0; I guess the info that you gave is fine; many thanks for your help guys!
