Servlets
Servlets are Java-based server-side components that extend the capabilities of web servers to generate dynamic content. They handle HTTP requests and responses, enabling the creation of interactive web applications by processing data, interacting with databases, and producing HTML, XML, or other formats. Servlets run within a servlet container, such as Apache Tomcat, which manages their lifecycle and provides a runtime environment.
Developers should learn Servlets when building enterprise-level Java web applications that require robust server-side logic, such as e-commerce sites, banking systems, or content management systems. They are essential for handling complex business logic, session management, and integration with Java EE technologies like JSP and JDBC, offering a scalable and portable solution for web development in Java environments.
