What is a Servlet in Java and how does it differ from other Java server-side technologies like JSP or JSF?
A Servlet in Java is a class that extends the capabilities of servers and responds to HTTP requests. It is used for creating dynamic web applications using Java. Servlets are server-side technologies that handle requests and generate responses.
Servlets differ from JSP (JavaServer Pages) and JSF (JavaServer Faces) in their architecture and approach. While Servlets are Java classes that can generate dynamic content directly, JSP allows embedding Java code in HTML templates for dynamic content generation. JSF, on the other hand, is a higher-level framework that provides a component-based approach to building web applications.
Servlets are more low-level and provide finer control over the request processing compared to JSP and JSF. They are often used in conjunction with JSP or other technologies to create robust web applications.
In summary, Servlets in Java are a fundamental building block for server-side programming, while JSP and JSF offer higher-level abstractions and approaches for web application development.
