关于struct2 datetimepicker的取值问题

JSP：
<sx:datetimepicker label="Project End Date" name="project.project_enddate" displayFormat="yyyy-MM-dd"></sx:datetimepicker>

action：
String result = this.request().getParemeter("project.project_startdate");

result始终为null

求问为什么 --------------------编程问答-------------------- String result = this.request().getParemeter("project.project_startdate");
改为
String result = this.request.getParemeter("project.project_startdate"); --------------------编程问答--------------------

String result = this.request().getParemeter("project.project_startdate");
改为
String result = this.request.getParemeter("project.project_startdate");

。。。。。。。在eclipse中根本都无法删掉那个括号 --------------------编程问答-------------------- 完整action看下 --------------------编程问答--------------------

完整action看下

其它的parameter都能get到的，比如
<tr>
<td colspan="2"><s:textfield name="project.project_name" label="Project Name"/></td>
</tr>

这个就是可以通过getParameter 来get到，为什么就是datetimepiker不可以 --------------------编程问答-------------------- <sx:datetimepicker label="Project End Date" name="project.project_enddate" displayFormat="yyyy-MM-dd"></sx:datetimepicker>

action：
String result = this.request().getParemeter("project.project_startdate");

你在开玩笑？看红色的东西，都不一致

--------------------编程问答-------------------- 不是说过
String timelimit = this.request().getParameter("project.project_startdate");
改为
String timelimit = this.request().getParameter("project.project_enddate");吗？
action直接
project.getProject_enddate()；没有值吗？
典型的struts封装对象的应用。 --------------------编程问答--------------------

改了还是没用
我已经不用这个，百度里好多人都有这个问题，我已经换了另外的方式，不过还是谢谢您了，我是新手，不太懂 --------------------编程问答-------------------- 你为啥用这个，无语了，直接用mydate97不就好了， --------------------编程问答-------------------- 貌似 datetimepicker 是标签
