DynaValidatorForm problem

Hi,
I'm trying to implement the Commons validator framework on my project but I am having a few problems. I am using the DynaValidatorForm to validate my forms. At the moment I am just trying to make it work on a logon form. Here are the files I'm using.
The error that I am getting at the moment is this.
2003-11-27 15:42:48,837 [ERROR] org.apache.commons.validator.Validator: reflection: org.apache.struts.validator.FieldChecks.validateRequired(java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org.apache.struts.action.ActionMessages, javax.servlet.http.HttpServletRequest)

private static Log logger = LogFactory.getLog(LoginAction.class);
public TestLogonAction()

super();
}
/**

public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws ServletException
{
logger.debug("Entering execute method of LoginAction");
DynaValidatorForm f = (DynaValidatorForm) form;
String person = (String) f.get("username");
logger.debug("Entering execute method of LoginAction ====>"+f);

return mapping.findForward("success");
}
}

Any help with this would be greatly appreciated!
Thanks!
