struts 问题！！！！！！！！！！！！！

wenjie2010

我在Action中有这样的代码：
msg=new ActionMessages();
msg.add(ActionMessages.GLOBAL_MESSAGE,new ActionMessage(GenerateProperty.VALIDATE_FAILD));
saveMessages(request, msg);[/size]
而在jsp页面中有

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

总出现这样的错误：
