Professional Java Servlets 2.3

Overview

This appendix describes the Java classes and interfaces defined in the Servlet 2.3 specification. These are contained in two packages:

• javax.servlet contains classes and interfaces related to servlet programming

• javax.servlet.http contains classes and interfaces related specifically to servlets using the HTTP protocol

In many cases, the actual objects passed will be instances of container-specific implementations of interfaces specified here, or concrete subclasses of abstract classes specified here.
