com.bea.web.tag
Class IdentifierTagSupport
java.lang.Object
javax.servlet.jsp.tagext.TagSupport
com.bea.web.tag.AbstractInputTagSupport
com.bea.web.tag.IdentifierTagSupport
- All Implemented Interfaces:
- IterationTag, Serializable, Tag
- public class IdentifierTagSupport
- extends AbstractInputTagSupport
- implements 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.
