java.lang.IllegalArgumentException: The servlets named [X] and [Y] are both mapped to the url-pattern [/url] which is not permitted

Question

I tried to add this servlet

package com.classmgt.servlet;

@WebServlet(\"/ControllerServlet\")
public class ControllerServlet extends HttpServlet {}
         


        

Answer 1

The servlets named [Register] and [com.TeamWork.controller.Register] are both mapped to the url-pattern [/Register] which is not permitted

getting this error you have to remove your servlet mapping from web.xml and just add @WebServlet("/Register") annotation + url

     Register
     com.TeamWork.controller
  

then your servlet class on the top add this one

@WebServlet("/Register")`
public class Register extends HttpServlet { }

it will work thanks
