The problem is that errors are normally saved in request scope, and a redirect would cause a new request scope to be created.
It is now possible to save errors to session scope, but I don't think anyone has done anything so that you could rig up the framework to do the validation for you and have that happen. But if you move the validation into your action, I think you can get where you're trying to go.
Another thing you might try would be to do it on the client side:
<logic:messagesPresent >
<a name="errors">You have errors</a> <br>
<html:messages id="msg"><div class="error"><c:out value="${msg}" /></div></html:messages>
</logic:messagesPresent >
and then way down at the bottom of your page...
<logic:messagesPresent >
<script>
location.hash='errors';
</script>
</logic:messagesPresent >(I've never actually used location.hash, but a quick check of the JS/DHTML cookbook suggests that its the right syntax. Note that you are explicitly intended to leave out the "#" mark in the value to location.hash.)

I have a JSP page in my application that consists of several lines of explanatory text (a screen's worth or so) followed by a form. When the user submits the form, the ActionForm validate method is called and, if there are errors, the user is returned to the same JSP page where html:errors displays the relevant error messages between the initial explanatory text and the beginning of the form. All this works fine. However, when the JSP page redisplays in this validation error scenario, I'd like the browser page to jump to the error messages.
Here is what I tried that did not work. Within the JSP page ... <a name="errors"><html:errors/></a> In struts-config action mapping, for the "input" attribute of the "action" element ... input="/flts/reservationlab.jsp#errors"
When I submit the form with a required field missing, I get ... The requested resource (/flts/reservationlab.jsp#errors) is not available.
Is there any way I can set up an action mapping so that, if control is redirected back to the "input" JSP page, I can make it so that the browser jumps to a named anchor tag ("errors" in this particular case)?
Thanks. --Jim
