在项目登录页面：

当验证码输入有误时，应该提示：验证码输入有误，请重新输入，但是页面出现乱了！

错误原因：

在产生错误信息时，页面中增加了<ul> <li><span></span></li></ul>标签，该如何修改改，

解决方法（一）：

在项目的src下，新建文件夹：template.simple，在文件夹里面放修改好的fielderror.ftl文件。

fielderror.ftl 代码：

这样，就ok了，重新发布项目，看结果如下：

解决方法（二）：

也可以在jsp页面中修改，效果是一样的。代码如下：

<TR><span style="white-space:pre"></span><TD class="td">验 证 码：</TD><TD class="td"><input name="checkNum" type="text" value="" id="checkNum" style="width: 80"><span style="white-space:pre"></span><img id="checkNumImage" src="${pageContext.request.contextPath}/image.jsp" height="19" align="absmiddle" onClick="changeCheckNum()"  title="点击换一张" style="cursor:hand">

<span style="white-space:pre"></span></TD><span style="white-space:pre"></span><td><s:fielderror fieldName="checkNum"/></td>

</TR>

把错误提示信息和验证码，图片放在一行里面。
