Rendering a Button with the h:commandButton Tag

If you are using a commandButton component tag, the data from the current page is processed when a user clicks the button, and the next page is opened. Here is an example of the h:commandButton tag:

<h:commandButton value="Submit"
     action="#{cashier.submit}"/>

Clicking the button will cause the submit method of CashierBean to be invoked because the action attribute references this method. The submit method performs some processing and returns a logical outcome.

The value attribute of the example commandButton tag references the button’s label. For information on how to use the action attribute, see Referencing a Method That Performs Navigation.
