Method Details- 
initDescription copied from class:jakarta.servlet.GenericServletCalled by the servlet container to indicate to a servlet that the servlet is being placed into service. SeeServlet.init(jakarta.servlet.ServletConfig).This implementation stores the ServletConfigobject it receives from the servlet container for later use. When overriding this form of the method, callsuper.init(config).- Specified by:
- initin interface- Servlet
- Overrides:
- initin class- HttpServlet
- Parameters:
- config- the- ServletConfigobject that contains configuration information for this servlet
- Throws:
- ServletException- if an exception occurs that interrupts the servlet's normal operation
- See Also:
 
- 
getServletInfoDescription copied from class:jakarta.servlet.GenericServletReturns information about the servlet, such as author, version, and copyright. By default, this method returns an empty string. Override this method to have it return a meaningful value. SeeServlet.getServletInfo().- Specified by:
- getServletInfoin interface- Servlet
- Overrides:
- getServletInfoin class- GenericServlet
- Returns:
- String information about this servlet, by default an empty string
 
- 
destroypublic final void destroy()Description copied from class:jakarta.servlet.GenericServletCalled by the servlet container to indicate to a servlet that the servlet is being taken out of service. SeeServlet.destroy().- Specified by:
- destroyin interface- Servlet
- Overrides:
- destroyin class- GenericServlet
 
- 
servicepublic final void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException Entry point into service.- Overrides:
- servicein class- HttpServlet
- Parameters:
- request- the- HttpServletRequestobject that contains the request the client made of the servlet
- response- the- HttpServletResponseobject that contains the response the servlet returns to the client
- Throws:
- ServletException- if the HTTP request cannot be handled
- IOException- if an input or output error occurs while the servlet is handling the HTTP request

jspInitpublic void jspInit()Description copied from interface:jakarta.servlet.jsp.JspPageThe 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.

jspDestroypublic void jspDestroy()Description copied from interface:jakarta.servlet.jsp.JspPageThe 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:
- jspDestroyin interface- JspPage
 
- 
_jspDestroyprotected void _jspDestroy()

_jspServicepublic abstract void _jspService(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException Description copied from interface:jakarta.servlet.jsp.HttpJspPageThe _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:
- _jspServicein interface- HttpJspPage
- Parameters:
- 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.
