How to Pass Data from JSP to Servlet

Passing data from a JSP (JavaServer Pages) to a Servlet is a common task in Java web development. This guide will walk you through the process in a way that’s easy to understand, especially if you’re a college student just starting with Java web applications.


Step-by-Step Guide

Let’s break down the process into simple steps:

  1. Create a JSP Form
  2. Set Up a Servlet
  3. Run and Test Your Application

Step 1: Create a JSP Form

First, you need a JSP page with a form where users can input data. This form will send data to the servlet.

Example JSP (index.jsp):

<%@ page language="java" contentType="text/html; charset=UTF-8" %>
<!DOCTYPE html>
    <title>Data Input Form</title>
    <h1>Enter Your Details</h1>
    <form action="DataServlet" method="post">
        Name: <input type="text" name="name"><br>
        Age: <input type="text" name="age"><br>
        <input type="submit" value="Submit">

In this form:

  • The action attribute specifies the servlet URL pattern (DataServlet).
  • The method attribute is set to post for secure data transmission.
  • Input fields for name and age are provided for user input.

Step 2: Set Up a Servlet

Next, create a servlet that will handle the data submitted from the JSP form.

Example Servlet (

package com.codersathi;


import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

 * Servlet implementation class DataServlet
public class DataServlet extends HttpServlet {

	protected void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		// Retrieve data from the request
		String name = request.getParameter("name");
		String age = request.getParameter("age");

		// Set response content type
		PrintWriter out = response.getWriter();

		// Generate response
		out.println("<h1>Received Data</h1>");
		out.println("<p>Name: " + name + "</p>");
		out.println("<p>Age: " + age + "</p>");


In this servlet:

  • The doPost method handles POST requests from the JSP form.
  • request.getParameter("name") retrieves the value of the name input field.
  • request.getParameter("age") retrieves the value of the age input field.
  • The servlet generates an HTML response displaying the received data.

Step 3: Run and Test Your Application

3.1. Run your application

Use an IDE like Eclipse or IntelliJ IDEA to deploy your web application to a servlet container like Apache Tomcat.

3.2. Access the JSP Form

Open your web browser and navigate to http://localhost:8080/YourProjectName/index.jsp.

3.3. Submit Data

Enter data in the form fields and click Submit button to send data to Servlet.

3.4. View the Response

The servlet processes the submitted data and displays it in the browser.
