Direct Known Subclasses:

InputPasswordTag

public class InputTextTag
extends InputTagSupport
implements BodyTag

Tag that generates HTML form fields of type <input type="text" name="foo" value="bar"/>, which can dynamically re-populate their value. Text tags may have only a single value, whose default may be set using either the body of the tag, or using the value="" attribute of the tag. At runtime the contents of the text field are determined by looking for the first non-null value in the following list:

• A value with the same name in the HttpServletRequest
• A value on the ActionBean if an ActionBean instance is present
• The contents of the body of the tag
• The value attribute of the tag
