Using the Core Tags

The tags included in the JavaServer Faces core tag library are used to perform core actions that are independent of a particular render kit. These tags are listed in Table 18-1.

Table 18-1. The `jsf_core` Tags

Tag Categories	Tags	Functions
Event-handling tags	`actionListener`	Registers an action listener on a parent component
`valueChangeListener`	Registers a value-change listener on a parent component
Attribute configuration tag	`attribute`	Adds configurable attributes to a parent component
Data conversion tags	`converter`	Registers an arbitrary converter on the parent component
`convertDateTime`	Registers a `DateTime` converter instance on the parent component
`convertNumber`	Registers a `Number` converter instance on the parent component
Facet tag	`facet`	Signifies a nested component that has a special relationship to its enclosing tag
Localization tag	`loadBundle`	Specifies a `ResourceBundle` that is exposed as a `Map`
Parameter substitution tag	`param`	Substitutes parameters into a `MessageFormat` instance and adds query string name-value pairs to a URL
Tags for representing items in a list	`selectItem`	Represents one item in a list of items in a `UISelectOne` or `UISelectMany` component
`selectItems`	Represents a set of items in a `UISelectOne` or `UISelectMany` component
Container tag	`subview`	Contains all JavaServer Faces tags in a page that is included in another JSP page containing JavaServer Faces tags
Validator tags	`validateDoubleRange`	Registers a `DoubleRangeValidator` on a component
`validateLength`	Registers a `LengthValidator` on a component
`validateLongRange`	Registers a `LongRangeValidator` on a component
`validator`	Registers a custom validator on a component
Output tag	`verbatim`	Generates a `UIOutput` component that gets its content from the body of this tag
Container for form tags	`view`	Encloses all JavaServer Faces tags on the page

These tags are used in conjunction with component tags and are therefore explained in other sections of this tutorial. Table 18-2 lists the sections that explain how to use specific jsf_core tags.
