These objects are accessible from JSP expressions and JSP scriptlets. You read about these objects later in this chapter. JSP Declarations As with any programming language, JSP uses variables to hold program data or code that performs various tasks. One JSP feature that makes variables or program code known to the JSP page is called a JSP declaration. JSP declarations have the following format: In Listing 4-2 you see a simple page with a JSP declaration and expression.
