component, you should first check to see that you are not reinventing the wheel You should consider the following before embarking on custom development: Customization may not be necessary because the JSF community may already have a solution fulfilling your needs Consult the component directory section of http://jsfcentralcom/ or do a Web search for jsf component libraries Your requirements may not rise to a level that requires a custom component Remember, a component is something that has a behavior and an appearance If the goal is to simply create a dynamic portion of content, and you don t need listeners, events, or other behaviors, Facelet templating may be all you need Certain customization can also be attained without having to build an entirely new UI component In many cases it is possible to write some custom logic such as a Validator or a Converter that can then be applied to one of the existing (standard) UI components Once an adequate amount of research has been performed and a solution that fits your requirements is still not found, then it is logical to proceed with custom JSF component development

As stated in 7, a user interface component (UI component) is a specific type of component that displays user interface content that the user can modify over time This content ranges from simple input fields or buttons to more complex items, such as trees or datagrids The part of the definition that reads content that the user can modify over time is the most important difference between something that is a UI component and something that is not a UI component For example, when a user checks a checkbox, he expects it to stay checked until he unchecks it, but when the user views a page with a navigation menu on the left, that navigation menu generally stays the same regardless of what the user is doing elsewhere in the page In other words, the component has a current state Of course, it s not hard to imagine a dynamic navigation menu whose contents depend on other parts of the page, but the minute your navigation menu needs such behavior, it ceases being a mere part of the page and becomes a UI component In the simplest terms, a UI component is something that has appearance, state, and behavior, and that can be reused in a variety of different contexts Let s take a step back and get some perspective Most JSF end users don t really care so much about what is and is not a component They have a page they see in the browser, and some of the things in the page respond to mouse clicks and keystrokes and some of the things in the page do not JSF page authors see a component as a tag they can stick in the page and have it display something useful, such as the login panel in the preceding chapter, which is shown by putting the tag <vt:loginPanel /> in the page JSF component authors see a component as a collection of other JSF elements, such as a UIComponent class, a Converter,
