All Implemented Interfaces:

Serializable, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.Tag

public class EmailTagSupport
extends AbstractInputTagSupport
implements Serializable

Provides the rendering logic for an HTML form field that accepts email address values only. In addition, each instance of this class uses an instance of com.bea.web.validation.EmailWord to perform runtime validation of the value for this field. This class places an EmailWord 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 EmailWord to validate user input passed in the HTTP request for this form field.
