abstract class <B>JspFactory</B><DT>extends java.lang.Object</DL><P><p> 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. <p> A conformant JSP Engine implementation will, during it's initialization instantiate an implementation dependent subclass of this class, and make it globally available for use by JSP implementation classes by registering the instance created with this class via the static <code> setDefaultFactory() </code> method. <p> The PageContext and the JspEngineInfo classes are the only implementation-dependent classes that can be created from the factory. <p> JspFactory objects should not be used by JSP page authors.<P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><A
