Java EE - HTTP Error 404 - resource is not available - after hitting "Submit" button on page

Question

My web program will allow a user to enter first name and last name and after the user press the submit button, it will print the first name and last name.

I receive an HTTP error 404 after the user presses the "Submit" button.

Error

This is my File structure

My codes

PrintFormContent.java

package form;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.*;

@WebServlet("/PrintFormContent")
public class PrintFormContent extends HttpServlet {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#HttpServlet()
     */
    public PrintFormContent() {
        super();
    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
    }

    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        String fname = request.getParameter("name");
        String lname = request.getParameter("lname");

         try{
                response.setContentType("text/html");
                PrintWriter out = response.getWriter();
                out.print("<p>First Name</p>" + fname);
                out.print("<p>Last Name</p>" + lname);

            }catch(IOException e){
                e.printStackTrace();
            }   }
}

you declared your servlet to PrintFormContent but you send your request to /testForm/form/PrintFormContent. You need to change it in the form-declaration:

<form id="PrintFormContent" name="PrintFormContent" role="form"
    action="/PrintFormContent" method="POST">

btw. don't forget to change parameter name in the servlet to fname:

String fname = request.getParameter("fname");

try to add this to web.xml, somehow your anotation seems not to work

<servlet-mapping>
   <servlet-name>PrintFormContent</servlet-name>
   <url-pattern>/PrintFormContent</url-pattern>
</servlet-mapping>

check this, maybe you have the same problem: webservlet-annotation-doesnt-work-with-tomcat-8

doesn't work. I even tried changing to @WebServlet("/testForm/form/PrintFormContent") also doesn't work – user3820292 Dec 10 '16 at 13:21
hmm, can you try to add a `System.out.println("test");` to the `doGet()` function and then call `localhost:8080/PrintFormContent` in your browser and check in the log, if you see "test" – JohnnyAW Dec 10 '16 at 13:25
@user3820292 see my update – JohnnyAW Dec 10 '16 at 13:30
I solved it. thanks – user3820292 Dec 10 '16 at 14:01
