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