Introduction
JSF stands for Java Server Faces and is a User Interface component based on the Java MVC framework. It aids in the creation of user interfaces for server-based applications. Java Server Faces a large component library that may be used to define an application's architecture. It includes:
- A rendering model specifies how the components should be rendered in various ways.
- A conversion model specifies how data converters should be registered on a component.
- An event and listener paradigm that specifies how component events should be handled.
- A validation model that specifies how validators should be registered on a component.
JSF Components
User Interface Components, Renderers, Convertors, Managed Beans, Events and Listeners, Validators, and Page Navigations, are all important components in a JSF application. This section will look at various UI components in greater depth.
JSF enables developers to build Web applications out of collections of UI components that can render themselves in various ways for various client types (for example - HTML browser, wireless, or WAP device).
JSF supports the following features:
- Core library
- Standard HTML input elements make up a set of base UI components.
- The base UI components can be extended to construct additional UI component libraries or enhance existing components.
- JSF UI components have many rendering capabilities that allow them to render differently depending on the client type.
There are two types of components:
- Standard UI Components: Text fields, list boxes, checkboxes, labels, panels, radio buttons, and other elements will be present in standard UI components.
- Custom UI Components: Users can design and utilize Reusable components that are included in custom components.
Now we are going to discuss the custom UI components in JSF:
