Richfaces is a rich Java Server Faces library which allows easy integration of Ajax capabilities in your Web application. Before now we have published two tutorials about Richfaces which can be used as introduction and as reference for installing: Let’s see how to achieve this, starting with simple examples:.
In practice, you turn a simple Richfacs component into an Ajax component. For example, in this code snippet you are recalling the method reverseIt each time there’s an event onkeyup on the inputText:.
Notice the reRender attribute which specifies the components which need to be updated after the action has been completed. In our sample, only the outputText named “reversed” will be updated.

Let’s see the a4j: Limiting the amount of data to send So far we’ve seen how Ajax can be useful because only a partial rendering of the Web page is rrichfaces, instead of the whole page.
However we’re still sending to the server all fields contained in the form.
This can lead to a decrease of performance if we are not using all of them. See the following example:. In this example, when you click on the commandButton “two”, since it’s contained in a a4j: When regions are nested, the region that encloses the Ajax component that initiated the request will be used.
The same result can be obtained by using the ajaxSingle attribute on the single component. This way, only that component will push data to the server. The equivalent code, using the ajaxSingle attribute is:.
The main difference with the commandButton and commandLink is that the request is fired automatically to the server on a configurable interval.
