What is JavaServer Faces (JSF) and its key features?

JavaServer Faces (JSF) is a Java web application framework that simplifies the development of user interfaces for Java EE applications. It is a component-based MVC framework that provides reusable UI components and event-driven programming model.

Key Features of JavaServer Faces (JSF):

• Component-Based Architecture: JSF allows developers to build web applications using reusable UI components, leading to faster development and maintenance.
• Managed Bean Support: JSF provides managed beans to manage application data and logic, making it easier to handle user input and business logic.
• Event-Driven Programming Model: JSF is based on the event-driven programming model, where user interactions trigger events that are handled by the framework.
• Integration with Java EE: JSF seamlessly integrates with other Java EE technologies such as EJB, JPA, and JAX-RS, making it a robust choice for enterprise applications.
• Rich UI Component Library: JSF comes with a rich set of built-in UI components that can be easily customized and extended to meet specific requirements.

Overall, JavaServer Faces (JSF) is a powerful framework for building Java web applications with a focus on reusability, maintainability, and scalability.
