Overview

The JavaServer Pages (JSP) Expression Language (EL) is a simple non-procedural scripting language that can be used to evaluate dynamic expressions within a JSP page. This refcard focuses on the Expression Language as applied to JSP pages. The EL described here is a subset of the fuller Unified Expression Language that applies to not only JSP pages, but also to JavaServer Faces (JSF) pages. To keep this refcard focused on JSP, JSF-only aspects have not been included.

Features include Using the EL in a JSP Page, Literal Values, Introducing Scoped Variables, Grabbing JavaBean Properties, Hot Tips and more.
