Hi, my servletConfig gives me null...
this is my
servlet
:
package lp; import java.io.IOException; import java.io.PrintWriter; import javax.servlet.ServletConfig; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * Servlet implementation class servv */ @WebServlet("/servv") public class servv extends HttpServlet { private static final long serialVersionUID = 1L; /** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) */ protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ServletConfig config = getServletConfig(); String nj = config.getInitParameter("name"); PrintWriter out = response.getWriter(); out.print(nj); } }
this is my web.xml:
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> <display-name>servletconfiganno</display-name> <servlet> <servlet-name>iu</servlet-name> <servlet-class>lp.servv</servlet-class> <init-param> <param-name>name</param-name> <param-value>trapti</param-value> </init-param> </servlet> </web-app>
