Instantiating Struts-provided ActionForm class directly instead of instantiating a class derived off ActionForm. This mightoccur implicitly if you specify that a form-bean is this Struts ActionForm class rather than specifying a child of this classfor the form-bean.
Not associating an ActionForm-descended class with an action can also lead to this error.
