I have to do a project for my web programming class where we create a html file that contains four text boxes, first and last name, address and zipcode, along with a submit button. along with this I need to create a java servlet file which prints out the user's inputs. I need to use the post method to pass the data from html to the java servlet and also use both doGet and doPost methods in the servlet. I think, but unfortunately I have a terrible teacher and I can't figure out the rest. So, if anyone can help me so I can see how to connect the two I would be very greatful.

Hi Friend,
Try the following code:
1)callServlet.html:
<html>
<center><h3>Form</h3></center>
<form method="post" action="http://localhost:8080/examples/Servlet">
<center>
<table>
<tr><td>First Name:</td><td><input type="text" name="firstname" size="20"></td></tr>
<tr><td>Last Name:</td><td><input type="text" name="lastname" size="20"></td></tr>
<tr><td>Address </td><td><input type="text" name="address" size="20"></td></tr>
<tr><td>Zip Code </td><td><input type="text" name="zip" size="20"></td></tr>
<tr><td><input type="submit" value="Submit" name="B1"></td><td><input type="reset" value="Reset" name="B2"></td></tr>
</table>
</center>
</form>
</html>
2)Servlet.java:
import java.io.*;
import java.sql.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Servlet extends HttpServlet {
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String fname=request.getParameter("firstname");
out.println("Firstname: "+fname+"<br>");
String lname=request.getParameter("lastname");
out.println("Lastname: "+lname+"<br>");
String address=request.getParameter("address");
out.println("Address: "+address+"<br>");
String zip=request.getParameter("zip");
out.println("Zip Code: "+zip+"<br>");
}
public void doGett(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
}
}
3)Do servlet mapping in web.xml:
<servlet>
<servlet-name>Servlet</servlet-name>
<servlet-class>Servlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Servlet</servlet-name>
<url-pattern>/Servlet</url-pattern>
</servlet-mapping>
Note: Put you html file inside web application folder and servlet inside WEB-INF/classes folder of web application forlder.
Thanks
