                                <s:hidden name="roles" ></s:hidden>/、/删除这一句不报错，不删除就报错
                                <table>

                                        <td class="tdFormLabel">姓名</td>
                                        <td class="tdFormControl"><s:textfield name="name"
                                                cssClass="text" /></td>

No result defined for action zd_authority.struts2.action.UserAction and result input.

貌似是action的配置有问题呀，你把代码贴完整一点吧。另外在action中增加一个name为input的result试试吧。
希望对你有帮助
