The HttpJspPage interface describes the interaction that a JSP Page Implementation Class must satisfy when using the HTTP protocol.

The behaviour is identical to that of the JspPage, except for the signature of the _jspService method, which is now expressible in the Java type system and included explicitly in the interface.

public interface HttpJspPage extends JspPage {
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.

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.

Params:
  • request – Provides client request information to the JSP.
  • response – Assists the JSP in sending a response to the client.
Throws:
  • ServletException – Thrown if an error occurred during the processing of the JSP and that the container should take appropriate action to clean up the request.
  • IOException – Thrown if an error occurred while writing the response for this page.
