Jexl is an extension of JSTL expression language. You can read more about how it extends JSTL at http://jakarta.apache.org/commons/jexl/. If you're unfamiliar with JSTL take a look at http://java.sun.com/products/jsp/jstl/. In Jelly you can basically write Jexl expressions anywhere you like. You write them like "${expr}". The syntax is very simple, really. It's just like writing Java. I suggest you browse through the examples mentioned in the Jelly documentation and some of the unit tests written as Jelly scripts to get an idea of how to use them. Cheers, -- knut
