Mastering Servlets and JSP: Building Dynamic Web Applications with Java
Introduction:
Servlets and JavaServer Pages (JSP) are essential components of Java web development, offering developers powerful tools for building dynamic and interactive web applications. In this comprehensive guide, we will delve deeper into these technologies, exploring their intricacies and providing a wealth of examples to empower developers in harnessing their full potential.
Servlets:
Servlets are Java classes that extend server capabilities to respond to client requests. They serve as the bridge between web clients and servers, handling incoming requests and generating dynamic responses. Servlets operate on the server-side and are executed within a servlet container, such as Apache Tomcat or Jetty, which manages their lifecycle.
