The JavaServer Pages(tm) (JSP) 2.0 specification provides a portable API for evaluating "EL Expressions". As of JSP 2.0, EL expressions can be placed directly in the template text of JSP pages and tag files.
This package contains a number of classes and interfaces that describe and define programmatic access to the Expression Language evaluator. This API can also be used by an implementation of JSP to evaluate the expressions, but other implementations, like open-coding into Java bytecodes, are allowed. This package is intended to have no dependencies on other portions of the JSP 2.0 specification.
