## com.bea.web.tag
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.

  Overrides:
    `doStartTag` in class `javax.servlet.jsp.tagext.TagSupport`

### release

    public void release()

  Resets the internal state of this instance. This is called after this tag has rendered itself in the `doStartTag` method. This is needed because the tag handler will reuse this instance for every int tag on the page.
