How to Create Servlet in MyEclipse IDE?

Creating a Servlet in MyEclipse IDE allows developers to build and deploy Java-based web applications efficiently. With built-in support for servers like Apache Tomcat, MyEclipse simplifies the process of developing, configuring, and running Servlets.

Provides an integrated environment for creating and managing Servlets
Supports easy deployment on Apache Tomcat server
Simplifies configuration of web.xml and project structure

Prerequisites:

Install MyEclipse IDE
Install a Java-enabled Web Server (e.g., Apache Tomcat, GlassFish)
Configure Eclipse with Apache Tomcat server

Steps to Creating Servlet Program in MyEclipse

Follow the below steps to create and deploy a basic Servlet application in MyEclipse

Step 1: Create a Dynamic Web Project

Open MyEclipse, in the top menu, go to File -> New -> Web Project and click it to create a Web Project..

Click Web Project, enter the project name, and select Java EE version, Java version, and JSTL.
Choose or add the target runtime (Apache Tomcat), then click Next to proceed.

Choosing Servlet Project Details Myeclipse

After that a new screen will show source and classes folders.
keep the default settings and click Next.

Enter the context root and keep default settings; optionally select Generate web.xml or use @WebServlet.
Then click Next to continue with Maven configuration.

Configure Maven (enabled by default), enter Group ID and Artifact ID or keep defaults.
Then click Next to proceed.

Keep default dependencies selected and click Finish to create the project.
Ensure internet connection so Maven can download required dependencies.

After project creation, verify the project structure matches the expected setup.
You have successfully created the web project in MyEclipse.

Step 2: Create Servlet Class

Now, click on the Java Resources in the project tree of your project.
Right Click on the src/main/java folder and go to New -> Servlet.

A dialog will open -> enter the package name (proper naming) and servlet name.
Ensure it extends HttpServlet, then click Next to continue.

Creating login servlet details myeclipse

Enter servlet description and URL pattern (or keep default).
Click Next to continue.

Creating login servlet description myeclipse

Select required HTTP methods (GET, POST, etc.), and MyEclipse will generate doGet() and doPost().
You can also use init() and destroy(), then click Finish to create the servlet.

The servlet is created with boilerplate code, including a constructor and methods like doGet().
It uses @WebServlet annotation for URL mapping.

Step 3: Defining the servlet logic.

Configure the welcome page to collect username and password (using GET for demo).
Open index.jsp (src -> main -> webapp) and add the login form code.

HTML

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My Login page</title>
<style>
.row {
    margin: 1rem 0;
}
</style>
</head>

<body>
    <h1 class="row">Welcome to GeeksForGeeks!!!</h1>
    <div style="padding:20px">
        <form action="Login">
            <div class="row">
                <h3>Enter your username</h3>
                <input name="userName" type="text">
            </div>
            <div class="row">
                <h3>Enter your password</h3>
                <input name="password" type="password">
            </div>
            <div class="row">
                <button type="submit">Login</button>
            </div>
        </form>
    </div>
</body>
</html>

Open the servlet file and add code to read username and password from URL parameters and display them.
This is for demo only—avoid using URL parameters for sensitive data in real applications.

Java

package com.example;

import jakarta.servlet.ServletException;
import jakarta.servlet.annotation.WebServlet;
import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;

@WebServlet("/Login")
public class Login extends HttpServlet {
    private static final long serialVersionUID = 1L;
       
    public Login() {
        super();
    }
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html");
        PrintWriter out=response.getWriter();
        String userName=request.getParameter("userName");
        String password=request.getParameter("password");
        out.print("<html><body>");
        out.print("<h1>Hello!!!</h1>");
        out.printf("<h3>User Name with : %s </h3><h3>Your password is : %s</h3>",userName,password);
        out.print("</body></html>");
    }
}

Step 4: Running our project.

Right-click the project -> Run As -> MyEclipse Server Application and check console logs.
If configured properly, it will run on Tomcat without errors.

Output

After running, the project starts on Tomcat and may open in the browser.
If not, use http://localhost:8080/project_name then index.jsp loads by default.

After submitting the form, the mapped servlet is invoked.
It processes the request and displays the entered username and password.

Login page details entered servlet myeclipse

After submitting the form, the request is sent to the mapped servlet.
The output of form filled by the user visible to us.

Explanation: After submitting the login form, the servlet processes the request and displays the entered username and password on the browser.
