- * 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.
- *
- * <p><B>Two plus One Methods</B>
- * <p>
- * 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.
- * <p>
- * A class implementing this interface is responsible for invoking
- * the above methods at the appropriate time based on the
- * corresponding Servlet-based method invocations.
- * <p>
- * The jspInit() and jspDestroy() methods can be defined by a JSP
- * author, but the _jspService() method is defined automatically
- * by the JSP processor based on the contents of the JSP page.
- *
- * <p><B>_jspService()</B>
- * <p>
- * The _jspService()method corresponds to the body of the JSP page. This
- * method is defined automatically by the JSP container and should never
- * be defined by the JSP page author.
- * <p>
- * If a superclass is specified using the extends attribute, that
- * superclass may choose to perform some actions in its service() method
- * before or after calling the _jspService() method. See using the extends
- * attribute in the JSP_Engine chapter of the JSP specification.
- * <p>
- * The specific signature depends on the protocol supported by the JSP page.
- *
- * <pre>
- * public void _jspService(<em>ServletRequestSubtype</em> request,
- * <em>ServletResponseSubtype</em> response)
- * throws ServletException, IOException;
