<%-- ActionError --%>
<s:if test="hasActionErrors()">
<s:iterator value="actionErrors" id="error">
    <s:property value="error"/>
</s:iterator>
</s:if>

<%-- FieldError ---%>
<s:if test="hasFieldErrors()">
<s:iterator value="fieldErrors" id="error">
    <s:property value="error"/>
</s:iterator>
</s:if>

js 验证

<script type="text/javascript">
<!-- 
var sStr = "";
<s:if test="hasActionErrors()">
    <s:iterator value="actionErrors">
     sStr = sStr + "<s:property/>\r\n";
    </s:iterator>
</s:if>

<s:if test="hasFieldErrors()">
    <s:iterator value="fieldErrors">
     sStr = sStr + "<s:property value="value[0]"/>\r\n";
    </s:iterator>
</s:if>
if (sStr != "")
{
   alert(sStr);
}
