Interface JspPage

All Superinterfaces:
Servlet
Known Subinterfaces:
HttpJspPage

public interface JspPage
extends Servlet

This is the interface that a JSP processor-generated class must satisfy.

The interface defines a protocol with 3 methods; only two of them: jspInit() and jspDestroy() are part of this interface as the signature of the third method: _jspService() depends on the specific protocol used and cannot be expressed in a generic way in Java.

A class implementing this interface is responsible for invoking the above methods at the apropriate time based on the corresponding Servlet-based method invocations.

The jspInit(0 and jspDestroy() methods can be defined by a JSP author, but the _jspService() method is defined authomatically by the JSP processor based on the contents of the JSP page.

Method Summary

void
jspDestroy()
jsp_destroy() is invoked when the JspPage is about to be destroyed.
void

jsp_init() is invoked when the JspPage is initialized.
