public class ErrorsTag

extends javax.servlet.jsp.tagext.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.
