Java Servlet is the foundation web specification in the Java Enterprise Platform. Developers can build web applications using the Servlet API to interact with the request/response workflow.

A servlet is a small Java program that runs within a Web server. Servlets receive and respond to requests from Web clients, usually across HTTP, the HyperText Transfer Protocol. To implement this interface, you can write a generic servlet that extends javax.servlet.GenericServlet or an HTTP servlet that extends javax.servlet.http.HttpServlet.

Apr 11, 2025 · To create Java Servlets, we need to use Servlet API which contains all the necessary interfaces and classes. Servlet API has 2 packages namely, This package provides the number of interfaces and classes to support Generic servlet which is protocol independent.

Apr 17, 2025 · Java Servlet is a Java program that runs on a Java-enabled web server or application server. It handles client requests, processes them, and generates responses dynamically. Servlets are the backbone of many server-side Java applications due to their efficiency and scalability. Key Features: Servlets work on the server side.

Jan 1, 1970 · Servlets typically run on multithreaded servers, so be aware that a servlet must handle concurrent requests and be careful to synchronize access to shared resources. Shared resources include in-memory data such as instance or class variables and external objects such as files, database connections, and network connections.

The javax.servlet package contains a number of classes and interfaces that describe and define the contracts between a servlet class and the runtime environment provided for an instance of such a class by a conforming servlet container.

May 14, 2024 · Simply put, a Servlet is a class that handles requests, processes them and reply back with a response. For example, we can use a Servlet to collect input from a user through an HTML form, query records from a database, and create web pages dynamically. Servlets are under the control of another Java application called a Servlet Container.

In this article, I am going to discuss the Java Servlet API with Examples. Servlets are created using javax.servlet and javax.servlet.http

The javax.servlet package contains a number of classes and interfaces that describe and define the contracts between a servlet class and the runtime environment provided for an instance of such a class by a conforming servlet container.

Java Servlets, being lightweight and efficient, are an excellent choice for building RESTful APIs. In this article, we’ll explore how to create a RESTful API using Java Servlets, focusing on HTTP methods, JSON responses, and best practices for efficient development.
