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

Just remove the annotation @WebServlet("/ControllerServlet"), from the ControllerServlet, because it already added in the web.xml.
