Validation Based on the TLD

When the JSP container converts a JSP page to a servlet, it compares each custom action element to the specification of the action element in the TLD. First, it makes sure that the action name matches the name of an action specified in the TLD corresponding to the action element’s prefix. It then looks at the attribute list in the page and compares it to the attribute specification in the TLD. If a required attribute is missing or an attribute is used in the page but not specified in the TLD, it reports it as an error so the page author can correct the mistake. It also reports an error if a body is used for a custom action that is declared to be empty.
