{{main article|Jakarta Expression Language}}

Version 2.0 of the JSP specification added support for the Expression Language (EL), used to access data and functions in Java objects. In JSP 2.1, it was folded into the [[Unified Expression Language]], which is also used in [[JavaServer Faces]].<ref>[http://java.sun.com/products/jsp/reference/techart/unifiedEL.html The Unified Expression Language (Sun Developer Network)]</ref>

The JSP Expression Language uses a compact syntax which enables the developer to get attributes and JavaBean properties from a given request object. When using EL, a dollar sign ("$") must be added at the beginning of the code. The dollar symbol is followed by an opening brace ("{"), as well as a closing brace ("}"). The code is then written between the opening and closing braces.{{sfn | Murach | Urban | 2014 | loc=§2 Essential servlet and JSP skills - How to use EL to get attributes
