To become an expert Java developer, you must understand the 'why'. This guide takes you under the hood from first principles, building a server so you can truly grasp how frameworks like Spring work and build better applications. Key Features Build a multithreaded HTTP server and application container using Java sockets Understand and replicate the internal mechanics of Tomcat and Jakarta EE and Spring features Develop a modular Java framework with annotation-based routing and dependency injection Purchase of the print or Kindle book includes a free PDF eBook Book DescriptionEver wondered how a web server like Tomcat actually works or how frameworks like Spring handle requests? This book takes you beneath the surface of Java web development. Starting with low-level socket programming, you'll build a multithreaded HTTP server from the ground up and extend it into a lightweight application server capable of handling dynamic content. Along the way, you'll master HTTP request parsing, response generation, servlet-like request handling, and Java reflection and annotations for metaprogramming. As you progress, you'll evolve this infrastructure into your own Java framework with embedded Tomcat, annotation-driven routing, object serialization with Jackson, and basic dependency injection modeled on Jakarta CDI. Packed with practical examples and end-to-end projects - including building a dynamic temperature service and context-aware app container -this book is a complete guide to learning how modern Java web stacks function under the hood. Whether you're an educator, student, or seasoned Java developer, this hands-on journey will dramatically deepen your understanding of servers, frameworks, and the web architecture that powers everything online today. What you will learn Implement a multithreaded web server using Java sockets Decode and construct HTTP requests and responses manually Build an application container to serve dynamic Java classes Use reflection and annotations for routing and request mapping Serialize and deserialize JSON data using Jackson Structure projects with modular static and dynamic content Manage lightweight session handling and routing logic Create and deploy a complete custom Java web framework Who this book is forJava developers, computer science students, and educators seeking a deep, hands-on understanding of web server internals and application framework design. Prior knowledge of Java and basic networking concepts is recommended.
