<P>JSP也很简单，就是加入<s:token />标志。接下来是Actoin配置的XML片段：</P>

<P>以上XML片段值注意的是加入了“token”拦截器和“invalid.token”结果，因为“token”拦截器在会话token与请求token不一致时，将会直接返回“invalid.token”结果。</P>
<P>发布运行应用程序，在浏览器中键入：<A
href="http://localhost:8080/Struts2_CoolTags/token.jsp">http://localhost:8080/Struts2_CoolTags/token.jsp</A>，出现如下图所示页面：</P>
<P><IMG alt=正常显示的token.jsp页面
src="Strus 2的新表单标志的使用 - Max On Java - BlogJava.files/r_token1.gif"><BR><SPAN
style="FONT-SIZE: smaller; FONT-STYLE: italic">清单10 正常显示的token.jsp页面</SPAN></P>
<P>随便填点东西并提交页面，一切正常返回以上页面，然后按“F5”刷新页面，在弹出的对话框中点击“Retry”，出现如下图所示页面：</P>
<P><IMG alt=重复提交出错显示

<H2>4、<s:datetimepicker />、<s:optiontransferselect
/>和<s:updownselect /></H2>
<P>这几个标志的使用相对简单，所以我想小举一例即可，以下是JSP的代码：</P>
