Here is the HTML code:
<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Add Two Numbers</title></head><body><h1>Please enter numbers</h1><form action="AddNum" method="post"> Enter 1st Number :<br><input type=text name=num1><br><br> Enter 2nd Number :<br><input type=text name=num2><br><br><input type="submit"></form></body></html>Here is the java code:
package com.package1;import java.io.IOException;import java.io.PrintWriter;import jakarta.servlet.ServletException;import jakarta.servlet.annotation.WebServlet;import jakarta.servlet.http.HttpServlet;import jakarta.servlet.http.HttpServletRequest;import jakarta.servlet.http.HttpServletResponse;@WebServlet("/AddNum")public class Addserv extends HttpServlet{ private static final long serialVersionUID = 1L; @Override protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { // TODO Auto-generated method stub super.doPost(req, resp); int no1=Integer.parseInt(req.getParameter("num1")); int no2=Integer.parseInt(req.getParameter("num2")); int sum=no1+no2; PrintWriter out = resp.getWriter(); out.println(sum); } @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { doPost(req,resp); }}even though I used the doPost method, I am getting this error message.
I am using Eclipse for IDE and Apache Tomcat 10.1.30 as my server
I tried to add a doget method(still in code as I believe it doesn't negatively alter anything)
Tried changing the method of the form to "get", same 405 error with get instead of post.
