Servlet 3.0 server specifications

Question

Hi, i'm italian and sorry for my bad english.
I'm trying new servlet features expecially the "pluggability".(8.1.4 @WebListener)
In tutorial i can see this example:
@WebListener
public class MyListener implements ServletContextListener{
public void contextInitialized(ServletContextEvent sce) {
ServletContext sc = sce.getServletContext();
sc.addServlet("myServlet", "Sample servlet",
"foo.bar.MyServlet", null, -1);
sc.addServletMapping("myServlet", new String[] {
"/urlpattern/*" });
}however searching in API, function "addServlet" has two param instead four and "addServletMapping" daesn't exist.
I tryed with addServlet's right parameters and as I imagined, web.xml result corrupted when addServletMapping is called
how solve this problems?

Answer 1

solved, i found the right code
import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.ServletRegistration;
import javax.servlet.annotation.WebListener;
@WebListener
public class WebXmlManager implements ServletContextListener {
     public void contextInitialized(ServletContextEvent arg0) {
          ServletContext context = arg0.getServletContext();
          ServletRegistration.Dynamic dynamic = context.addServlet("test","core.Test");
          dynamic.addMapping("/Test");
}however there isn't any way to run the Programmatic definition of component for each request? i receive this exception : "Servlets can not be added to context /app as the context has been initialised"
