    • jspInit

      public void jspInit()
      Description copied from interface: JspPage
      The jspInit() method is invoked when the JSP page is initialized. It is the responsibility of the JSP implementation (and of the class mentioned by the extends attribute, if present) that at this point invocations to the getServletConfig() method will return the desired value. A JSP page can override this method by including a definition for it in a declaration element. A JSP page should redefine the init() method from Servlet.
      Specified by:
      jspInit in interface JspPage

    • _jspInit

      public void _jspInit()

    • jspDestroy

      public void jspDestroy()
      Description copied from interface: JspPage
      The jspDestroy() method is invoked when the JSP page is about to be destroyed. A JSP page can override this method by including a definition for it in a declaration element. A JSP page should redefine the destroy() method from Servlet.
      Specified by:
      jspDestroy in interface JspPage

    • _jspDestroy

      protected void _jspDestroy()

    • _jspService

      public abstract void _jspService(jakarta.servlet.http.HttpServletRequest request, jakarta.servlet.http.HttpServletResponse response) throws jakarta.servlet.ServletException, IOException
      Description copied from interface: HttpJspPage
      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.

      Specified by:
      _jspService in interface HttpJspPage
      Parameters:
      request - Provides client request information to the JSP.
      response - Assists the JSP in sending a response to the client.
      Throws:
      jakarta.servlet.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.
