JUEL is an implementation of the Unified Expression Language (EL), specified as part of the JSP 2.1 standard (JSR-245). Motivation: Once, the EL started as part of JSTL. Then, the EL made its way into the JSP 2.0 standard. Now, though part of JSP 2.1, the EL API has been separated into package javax.el and all dependencies to the core JSP classes have been removed.
