Implicit Variables
The JSP specification defines a number
of implicit scripting variables. Most of the implicit variables have
types defined by classes and interfaces in the Servlet
specification’s
javax.servlet.http package, but two are part of
the JSP javax.servlet.jsp package and one is part
of the Java core API. Scripting elements in a JSP page can use these
objects to access request and response information as well as objects
saved in one of the JSP scopes: page, request, session, and
application.
Most of these objects are also available to EL expressions through the EL implicit variables. The detailed sections include the EL expression in the Synopsis sections where applicable.
