You can write validate method while extending ValidatorForm. But it will become same as that of extending ActionForm.
ValidatorForm class extends ActionForm and provides basic field validation based on an XML file. The key passed into the validator is the action element's 'name' attribute from the struts-config.xml which should match the form element's name attribute in the validation.xml.
ValidatorForm used for declarative validations not for programatic validations.
