HTML Form Processing

The Java Web Toolkit provides the class

  public class Form extends CompoundItem

for HTML form processing. Since the Form class has been defined as a sub-class of CompoundItem, the addItem method can be applied to a Form object to populate it with various objects of the following types:

• CheckBox
• Radio
• Submit
• Reset
• TextField
• TextArea
• Select
• Hidden
• PasswordField

To create a Form object, the following steps must be taken:

• Create a form object, specifying the METHOD attribute (GET or POST), and the ACTION URL attribute.
• Populate the form object by creating one or more of the objects to be included in the form and add it to the form using the addItem method.
• Add the form object to the HtmlBody object.
