init
Description 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 interfaceServlet- Overrides:
initin classHttpServlet- Parameters:
config- theServletConfigobject that contains configuration information for this servlet- Throws:
ServletException- if an exception occurs that interrupts the servlet's normal operation- See Also:
-
getServletInfo
Description 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 interfaceServlet- Overrides:
getServletInfoin classGenericServlet- Returns:
- String information about this servlet, by default an empty string
-
destroy
public 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 interfaceServlet- Overrides:
destroyin classGenericServlet
-
service
public final void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException Entry point into service.- Overrides:
servicein classHttpServlet- Parameters:
request- theHttpServletRequestobject that contains the request the client made of the servletresponse- theHttpServletResponseobject that contains the response the servlet returns to the client- Throws:
ServletException- if the HTTP request cannot be handledIOException- if an input or output error occurs while the servlet is handling the HTTP request- See Also:
-
jspInit
public 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.
-
_jspInit
public void _jspInit() -
jspDestroy
public 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 interfaceJspPage
-
_jspDestroy
protected void _jspDestroy() -
_jspService
public 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 interfaceHttpJspPage- 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.
