PageContext extends JspContext to provide useful context information for
when JSP technology is used in a Servlet environment.
<p>
A PageContext instance provides access to all the namespaces associated
with a JSP page, provides access to several page attributes, as well as
a layer above the implementation details. Implicit objects are added
to the pageContext automatically.
<p> The <code> PageContext </code> class is an abstract class, designed to be
extended to provide implementation dependent implementations thereof, by
conformant JSP engine runtime environments. A PageContext instance is
obtained by a JSP implementation class by calling the
JspFactory.getPageContext() method, and is released by calling
JspFactory.releasePageContext().
<p> An example of how PageContext, JspFactory, and other classes can be
used within a JSP Page Implementation object is given elsewhere.
<p>
The PageContext provides a number of facilities to the page/component
author and page implementor, including:
<ul>
<li>a single API to manage the various scoped namespaces
<li>a number of convenience API's to access various public objects
<li>a mechanism to obtain the JspWriter for output
<li>a mechanism to manage session usage by the page
<li>a mechanism to expose page directive attributes to the scripting
environment
<li>mechanisms to forward or include the current request to other active
components in the application
<li>a mechanism to handle errorpage exception processing
</ul>
<p><B>Methods Intended for Container Generated Code</B>
<p>Some methods are intended to be used by the code generated by the
container, not by code written by JSP page authors, or JSP tag library
authors.
<p>The methods supporting <B>lifecycle</B> are <code>initialize()</code>
and <code>release()</code>
<p>
The following methods enable the <B>management of nested</B> JspWriter
streams to implement Tag Extensions: <code>pushBody()</code>
<p><B>Methods Intended for JSP authors</B>
<p>
The following methods provide <B>convenient access</B> to implicit objects:
<code>getException()</code>, <code>getPage()</code>
<code>getRequest()</code>, <code>getResponse()</code>,
<code>getSession()</code>, <code>getServletConfig()</code>
and <code>getServletContext()</code>.
<p>
The following methods provide support for <B>forwarding, inclusion
and error handling</B>:
<code>forward()</code>, <code>include()</code>,
and <code>handlePageException()</code>.</div>
