Join Ketkee Aryamane for an in-depth discussion in this video Expression language, part of Java EE: Servlets and JavaServer Pages (JSP).

So if you want to go ahead and dynamically read the data…of JavaBean components, or maybe read the data out of…any implicit objects that you have been storing it into,…that can be quickly read and displayed on a JSP with…simple expressions.…You can also invoke public methods and go ahead and…basically evaluate and print the output of those…expressions on the JSP page.…Not only this, expression language also allows you to…perform arithmetic, addition, subtraction, multiplication,…division, modulo, or for that matter relational,…
