Re: [s2] Problem getting basic server side field validation to work

[928572663]

Thanks David.

So are you saying that the struts2 validation framework requires one 
Action per JSP page?   If so, it seems like that needs to be included in 
the "full disclosure" section of the "validation" confluence page  :-)

If I don't want to go that route (1 Action : 1 JSP),  are there any 
alternatives short of writing my own validation framework?

Thanks,
John

Great - that fixed it.

Follow up:  supposed this Action class can serve up 10 different JSP 
pages, all of which need validation.   I would want the "input" result 
type to forward to whichever of the 10 JSPs that the user was in when 
the validation error occurred.   So what is the best way to handle that?

Thanks,
John

Yes, in the event of server-sided validation failure the framework
returns the user to this "input" page

Thanks David for the quick reply.

Is the 'input' result type used by the validation framework?  My
action 
class does not return that.

Thanks,
John

You need to define a <result> of type input for your action.

Subject: [s2] Problem getting basic server side field validation to
work
I'm trying to do a very basic test app that demonstrates the server
side
field validation and am getting an exception during initial JSP page 
rendering.  The page and action work fine without the validation.

Any ideas what I may be missing?

I've read the confluence pages on validation, and have been keeping
up
with the many posts on the mailing list, but they all seem to be
various
advanced scenarios.

Here is some info to help:

* Using struts 2.1.2 basic (no plugins to speak of)
* Using Zero Configuration (annotations) with no struts.xml
* form bean is stored in session
* action function works great w/o validation
* when adding the SampleAction-validation.xml the exception happens 
during initial page rendering

Here is the stack and last few logs:
