## Using Default Validators

In addition to the validators you declare on the components, you can also specify zero or more default validators in the application configuration resource file. The default validator applies to all `javax.faces.component.UIInput` instances in a view or component tree and is appended after the local defined validators. Here is an example of a default validator registered in the application configuration resource file:

    <faces-config>
        <application>
            <default-validators>
                <validator-id>javax.faces.Bean</validator-id>
            </default-validators>
        <application/>
    </faces-config>
