Re: Retrieving specific form validation error messages

[Erik Weber]

I see that the ActionErrors object is stored as a request attribute 
under the key "org.apache.struts.action.ERROR".

I would like to set a different CSS class for each <td> containing a 
field that has a property that is keyed in the ActionErrors instance. In 
pseudocode:

begin "username" field;
if (ActionErrors instance exists and ActionErrors instance contains any 
ActionErrors for the "username" property) {
open td with class set to "style B";
print prompt for username field;
print username field;
close td;
}
else {
open td with class set to "style A";
print prompt for username field;
print username field;
close td;
}

. . . and so on, for each field. This seemingly could get to be a lot of 
code. Any Struts/JSTL tag tricks I can use?

Thanks,
Erik

In a JSP containing a form, what is the easiest way to see if a form 
validation error message exists for a particular, say, html:text 
field, when that page is processing after form validation has failed? 
For example, what if you wanted to present the messages field by field 
instead of all together at the top of the page? I assume the error 
messages are keyed according to the value of the "property" attribute 
for each field, or something similar?

Thanks,
Erik
