    public class ErrorsTag

extends TagSupport

Custom tag that renders error messages if an appropriate request attribute has been created. The tag looks for a request attribute with a reserved key, and assumes that it is either a String, a String array, containing message keys to be looked up in the module's MessageResources, or an object of type `org.apache.struts.action.ActionErrors`.

The following optional message keys will be utilized if corresponding messages exist for them in the application resources:

- errors.header - If present, the corresponding message will be rendered prior to the individual list of error messages.
- errors.footer - If present, the corresponding message will be rendered following the individual list of error messages.
- errors.prefix - If present, the corresponding message will be rendered before each individual error message.
- errors.suffix - If present, the corresponding message will be rendered after each individual error message.
