Answer 1

You need to read the JSP specification, particularly section JSP.11.2.4 which sets out a number of requirements for the super class you use with extends and none of which are met by the super class in your question.

...the provided superclass:

• Implements HttpJspPage if the protocol is HTTP, or JspPage otherwise.
• All of the methods in the Servlet interface are declared final.

Additionally, it is the responsibility of the JSP page author that the provided superclass satisfies:

• The service method of the servlet API invokes the _jspService method.
• The init(ServletConfig) method stores the configuration, makes it available via getServletConfig, then invokes jspInit.
• The destroy method invokes jspDestroy.
