public class TextareaTagSupport

extends AbstractInputTagSupport

implements java.io.Serializable

Provides the rendering logic for an HTML form field for text areas In addition, each instance of this class uses an instance of com.bea.web.validation.Word to perform runtime validation of the value for this field. This class places a Word 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 Word to validate user input passed in the HTTP request for this form field.
