JSF is a framework that allows web developers to build user interfaces for JavaServer applications.
The full form of JSF is ” JavaServer Faces .” It is supported by web servers that are running Java Enterprise Edition (Java EE).
JSF simplifies the creation of Web Application, for which it provides a standard set of tools (or an API ) to build user interfaces.
For example, in HTML instead of coding an entire web form, a developer can easily call a simple JSF function that generates the form.
There is also a second JSF function that can be used to process the data entered by the user . These functions are processed in the server and the resulting data is produced at the output of the client’s browser.
JSF helps a lot of developers in which it provides reusable objects that can be easily inserted into webpages. By the way, these components are also very beneficial for website visitors because they provide standardized interface elements.
Since Java code is processed in the server, the appearance of the generated web pages is quite consistent across multiple websites. Additionally, JSF components are also tested on multiple platforms, so that they can work in all major browsers.
