Facelets

Facelets is a technology used in Java-based web applications to create dynamic, reusable user interfaces. Think of it as a template system that allows developers to design webpage layouts with modular components, making it easier to maintain and update the site. It works by combining static HTML with special tags and templates, enabling complex pages to be assembled efficiently. Facelets enhances the development process by providing a clear structure, reducing repetitive code, and supporting features like templating and component reuse, ultimately leading to more organized and flexible web applications.
