HTTP Status 405-http method POST is not supported by this URL another reason

Looking at other solutions on the web, finding out that their problems are not the cause of them, or finding out why:

@WebServlet ("/ce")
public class Ce extends HttpServlet {

protected void doget (HttpServletRequest request, httpservletresponse response)
Throws Servletexception, IOException {

}


protected void DoPost (HttpServletRequest request, HttpServletResponse response,int ID)
Throws Servletexception, IOException {
Doget (request, response);
}

}

I wrote in the back of the dopost a parameter int ID, may be in the program when added to the bar, careless of me, I hope you do not like me careless!
