Label

public class Label extends UIBean
Renders an HTML LABEL that will allow you to output label:name combination that has the same format treatment as the rest of your UI controls.

Examples

In this example, a label is rendered. The label is retrieved from a ResourceBundle via the key attribute giving you an output of 'User Name: Ford.Prefect'. Assuming that i18n message userName corresponds to 'User Name' and the action's getUserName() method returns 'Ford.Prefect'


<s:label key="userName" />



<s:label name="userName" label="User Name" />
