ActionMessages无法显示？

rottenapple 2007-05-24 11:30:28

新手上路，Struts1.1版本
有两个画面，Login.jsp and failure.jsp
我想在Login的Action中交验，出错的把错误信息在failure.jsp显示出来
但是怎么也显示不出来，求高手帮忙。
public class Register extends Action {

public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
ActionMessages errors = new ActionMessages();

ActionForward forward = new ActionForward();
// return value
RegistrationFormBean reg = (RegistrationFormBean) form;
if (reg.getAddress().length() < 5) {
errors.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage("message.item","Find Error"));
}

if (!errors.isEmpty()) {
this.saveMessages(request, errors);
forward = mapping.findForward("failure");

} else {

forward = mapping.findForward("success");
}

// Finish with
return (forward);

}
}
failure.Jsp

<html:messages id="msg" message="true">
<bean:write name="msg"/></html:messages>

id中的msg是什么？
在我印象当中<html:messages>变迁中的id属性应该为你saveMessage的第二个参数吧？在这里应该为errors吧？

反正在1.2当中我都是这么做的。。。
