public class IdentifierTagSupport

extends AbstractInputTagSupport

implements java.io.Serializable

Provides the rendering logic for an HTML form field that accepts Identifier values only. In addition, each instance of this class uses an instance of com.bea.web.validation.IdentifierWord to perform runtime validation of the value for this field. This class places a IdentifierWord instance in application scope, i.e. accessible via the ServletContext object. The ServletContext is shared by all servlets in a Web application. Consequently, the controller servlet can access the IdentifierWord to validate user input passed in the HTTP request for this form field.
