public class RadioButtonTag
extends AbstractCheckedElementTag

Databinding-aware JSP tag for rendering an HTML 'input' element with a 'type' of 'radio'.

Rendered elements are marked as 'checked' if the configured value matches the bound value.

A typical usage pattern will involved multiple tag instances bound to the same property but with different values.
