This might be heretical, but why can't you just call the form bean's validate
method from your action servlet. It still does the "business logic" of
validating the form and you'd still be able to validate your user.
ActionErrors errors = new ActionErrors();
MyForm myForm = (MyForm) form;
// validat user ...
// explicitly call the form's validate method
errors = myForm.validate();
// check to see if it returned errors
if ( !errors.empty() ) {
// save the specified error messages into the request
// so that you can use the <struts:errors> tag
saveErrors(request, errors);
// return to the original form
return ( new ActionForward( mapping.getInput() ) );
// or return ( mapping.findForward("failure") ) if you like
}
No?
