One can see that the logonForm (DynaValidatorForm) is a form bean for the action /logon. What is the purpose of using the DynaValidatorForm logonForm? Normally a form bean will do some checking. But I did see any of that function here.

The DynaVlidatorForm is a dynamic form which is created at runtime.
Hence you can not find the LoginForm class as would normally be created
along with the action class.

It can be used for simple forms.
