Java Web Development

Introduction to Java Web Technologies:

Java Web Development revolves around two powerful technologies – Servlets and JSP (JavaServer Pages). These technologies play a crucial role in creating dynamic, interactive, and robust web applications. While Servlets handle server-side processing, JSP allows developers to seamlessly embed Java code into HTML pages, facilitating a smooth user experience.

Building Web Applications with Java:

  • Servlets:

Servlets are Java classes that run on the server-side, processing client requests and generating dynamic responses. Acting as intermediaries between clients and server resources, they provide a foundation for web application development. Here’s a simple example of a Servlet that greets users based on their input:

import javax.servlet.*;
import javax.servlet.http.*;

public class GreetingServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out = response.getWriter();

String name = request.getParameter(“name”);
out.println(“<h2>Hello, ” + name + “!</h2>”);

  • JSP (JavaServer Pages):

JSP enables developers to create dynamic web content by embedding Java code within HTML. This approach enhances code maintainability and promotes a clear separation of concerns. Here’s an example of a simple JSP page that displays a dynamic greeting message:

<!DOCTYPE html>
<title>Greeting Page</title>
<h2>Hello, <%= request.getParameter(“name”) %>!</h2>
To use this JSP, you’ll need to configure the web.xml file to map the Servlet and JSP:



Java Web Development with Servlets and JSP empowers developers to create dynamic and interactive web applications. By harnessing the capabilities of these technologies, you can build feature-rich and scalable web solutions. Whether you’re a seasoned Java developer or just starting, exploring Servlets and JSP will open up a world of possibilities to create compelling web experiences.
