Issue
First of all, sorry if this question is a bit longer. I promise the code is super simple and fast to read.
I made a very simple app using Servlets. It has form where user picks beer color. It should take him to servlet I mapped to using XML. Servlet should just send a response back and print the color user picked.
Unfortunately, I have a bug somewhere and I can't understand where. Could someone help me, as I am really stuck?
There are my three files:
form.html:
<!DOCTYPE html>
<html>
<body>
<form action="SelectBeer.do" method="POST">
Color:
<select name="color">
<option>light</option>
<option>amber</option>
<option>brown</option>
<option>dark</option>
</select>
<button>Submit</button>
</form>
</body>
</html>
BeerSelect.java servlet:
package com.example.web;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class BeerSelect extends HttpServlet {
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
String color = req.getParameter("color");
out.println("Selected: " + color);
}
}
web.xml, that I used for mapping:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>MyBeerApp</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>myServlet</servlet-name>
<servlet-class>com.example.web.BeerSelect</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>myServlet</servlet-name>
<url-pattern>/SelectBeer.do</url-pattern>
</servlet-mapping>
</web-app>
Lastly, I will provide you with ss from my project structure. Once again, thanks in advance for anyone who tries to help. It would mean a lot to me!
P.S. Form runs fine, but when I submit it, I get 404 error.
Solution
@Stefan This is my project structure. I found it to be a bit different from you.
