Hi friends,

When the /editRegistration action is invoked, a registrationForm is created and added to the request, but its validate method is not called. The default value of the validate attribute is true , so if you do not want an action to trigger form validation, you need to remember to add this attribute and set it to false .

Hi friends,Yes. If your Action does not need any data and it does not need to make any data available to the view or controller component that it forwards to, it doesn't need a form. A good example of an Action with no ActionForm is the LogoffAction in the Struts MailReader application:

<action path="/logoff"
    type="org.apache.struts.webapp.example.LogoffAction">
    <forward name="success" path="/index.jsp"/>
    </action>

This action needs no data other than the user's session, which it can get from the Request , and it doesn't need to prepare any view elements for display, so it does not need a form.

However, you cannot use the tag without an ActionForm. Even if you want to use the tag with a simple Action that does not require input, the tag will expect you to use some type of ActionForm, even if it is an empty subclass without any properties.

Thanks.
