How to show validation errors as a list - struts2

Question

I have a simple login form with this code in jsp file:
<s:form
action="conexion" validate="true" theme="xhtml" target="formError">
<s:textfield name="username" key="profile.rut" />
<s:password name="password" key="profile.password" />
<s:submit id="boton_ingreso"/>
</s:form>
when that is rendered, it renders this way:
<form onreset="clearErrorMessages(this);clearErrorLabels(this);" method="post" target="formError" action="/AgendaPlus/conexion.action" onsubmit="return validateForm_conexion();" name="conexion" id="conexion">
<table class="wwFormTable">
<tbody><tr>
<td class="tdLabel"><label class="label" for="conexion_username">RUT:</label></td>
<td><input type="text" id="conexion_username" value="" name="username"></td>
</tr>
<tr>
<td class="tdLabel"><label class="label" for="conexion_password">Contraseña:</label></td>
<td><input type="password" id="conexion_password" name="password"></td>
</tr>
<tr>
<td colspan="2"><div align="right"><input type="submit" value="Submit" id="boton_ingreso" class="ui-button ui-widget ui-state-default ui-corner-all" role="button" aria-disabled="false">
</div></td>
</tr>
</tbody></table></form>
That way, when an error occurs, the error is shown above each field with error as a <tr> tag and since it is a table, I cannot style it to move to other place. I tried with target attribute of <s:form> tag but it did not work.

Answer 1

See the tag docs for fielderror:
<s:fielderror />
You know there are other themes, and that you can create your own, right?
For example, the "simple" theme doesn't render any tables or errors.
The target attribute seems a weird use for error reporting.
