Explanation
Facelets is the default templating system for JSF. It is a view technology that allows the creation of reusable templates for web pages. Facelets uses XHTML syntax and provides a more efficient and flexible way to build user interfaces compared to other templating systems. It supports component-based development and allows for easy integration with JSF's lifecycle and event model. Facelets also offers features like composition, templating, and reusability, making it a popular choice for building JSF applications.

In the MVC design pattern, the Model carries the login and data. The Model represents the data and business logic of the application. It is responsible for managing the data, validating user input, and performing the necessary calculations and operations. The Controller handles the user's interactions and updates the Model accordingly. The View is responsible for displaying the data from the Model to the user. Therefore, the Model is the component that carries the login and data in the MVC design pattern.

Explanation
Ajax is often used with JSF (JavaServer Faces) to enhance the user experience by allowing asynchronous communication between the client and server. Ajax enables dynamic updates of web pages without reloading the entire page, which is particularly useful in JSF applications where user interactions often require updating specific parts of the page. COBIT, Grails, and JCL are not commonly associated with JSF.
