legend don't work under of struts2

[red phoenix]

I want to use legend tag under struts2,I set legend css like follows:
form{
padding:10px;
margin:0 auto;
}
form#form legend {
border:1px solid #e8e7e1;
background:#fff url(../img/form_red.gif) repeat-x center left;
color:#a43708;
}

following code can run well:
<h3 id="adduser" style="width:100%;">Add user</h3>
<form id="form">
  <fieldset id="personal">
     <legend>information</legend>
  </fieldset>
</form>

Then I use <s:form> to replace <form> tag,like follows:
<h3 id="adduser" style="width:100%;">Add user</h3>
<s:form id="form">
  <fieldset id="personal">
     <legend>information</legend>
  </fieldset>
</s:form>

Then I find legend tag don't work! Why? How to correct above code to
make legned tag run again?

Thanks
