Custom Components in JSF
Ive been working as Java developer for more than 4 years now and I definitely can say that I'm not bored, I like my job. I want to think for it more like an art as John Romero says: " You might not think that programmers are artists, but programming is an extremely creative profession. It's logic-based creativity." Thats why I always try to personalize the technology stack I work with. You know, to give the code a little styling. Thats why when my colleagues asked me to give a Frydix talk the topic was easily chosen: Custom Components in JSF
The bases
Just a quick hint for the beginners. JSF (JavaServer Faces) is a Java-based web application framework intended to simplify development integration of web-based user interfaces. Whats great about JSF is that it provides developers with a powerful capability to define own custom components which can be used to render custom contents.
UI components in JSF
JSF provides developers capability to create web application from collections of UI components that can render themselves in different ways for multiple client types (for example HTML browser, wireless or WAP device).
- javax.faces.component.UIComponent
- Java class that is responsible for representing a self-contained piece of the user interface
- Renderer
- helper to the UIComponent that deals with how that specific UIComponent class should appear in a specific kind of client device.
The real deal
Ready to start? In the next slides youll learn how to use a custom renderer and when to/when not to use custom components. Youll see how to create:
- composite component
- custom tag
- custom validator
- custom converter
Enjoy!
