ps. My post added some "3D" text that isn't supposed to be there ...
Thanks Jeromy.
Yes I do have a <s:head> attribute, maybe not *exactly* but I have:
<s:head theme="ajax" />
Apologies for the confusion.
What I meant in my pevious post was that I had tried a few ways to do this
validation task.
In my initial post I had described one of these attempts which I think should
have worked.
What I am getting regardless of what sort of validation I try to implement is
this error:
java.lang.StringIndexOutOfBoundsException: String index out of range: -7
You mentioned the getters and setters for the fieldnames ... this only works
though if the fields are stored in the action right?
coz the fields I have aren't stored in the action, they are stored in a Form
class.
Ie my action looks something like:
public String execute() {
MyForm myForm = (MyForm)super.form;
String myField = myForm.getFieldName();
}
Markus: Thanks for your reply too, I am trying it right now. Just want this to
work grrr

The validate attribute here is used to enable client-side validation
only. That will only work if you include the <s:head> attribute in the
page.

You haven't mentioned whether you're using XML validation or
annotation-based validation. If by not working you mean "does nothing",
then your XML file is probably incorrectly named or your missing an
annotation. (You need to enable this separately from client-side
validation)
Whatever the case, the main difference between Struts1 and Struts2 here
is that Struts2 performs validation on the Object, not on the form
parameters.
That means, to check that "fieldName" is non-blank, it will call
getFieldName() after setFieldName() was called by the ParametersInterceptor.
A common problem is to forget the getter, but in that case Struts will
keep returning INPUT (validation failed) instead of invoking your action.
Hope that helps,
Jeromy Evans
