# Package javax.servlet.jsp

Classes and interfaces for the Core JSP 2.0 API.

The javax.servlet.jsp package contains a number of classes and interfaces that describe and define the contracts between a JSP page implementation class and the runtime environment provided for an instance of such a class by a conforming JSP container.

- Interface Summary
  Interface | Description
  --- | ---
  HttpJspPage | The HttpJspPage interface describes the interaction that a JSP Page Implementation Class must satisfy when using the HTTP protocol.
  JspApplicationContext | Stores application-scoped information for the JSP container.
  JspPage | The JspPage interface describes the generic interaction that a JSP Page Implementation class must satisfy; pages that use the HTTP protocol are described by the HttpJspPage interface.

- Class Summary
  Class | Description

  JspContext | `JspContext` serves as the base class for the PageContext class and abstracts all information that is not specific to servlets.
  JspEngineInfo | The JspEngineInfo is an abstract class that provides information on the current JSP engine.
  JspFactory | The JspFactory is an abstract class that defines a number of factory methods available to a JSP page at runtime for the purposes of creating instances of various interfaces and classes used to support the JSP implementation.
  JspWriter | The actions and template data in a JSP page is written using the JspWriter object that is referenced by the implicit variable out which is initialized automatically using methods in the PageContext object.
  PageContext | PageContext extends JspContext to provide useful context information for when JSP technology is used in a Servlet environment.
