Newbie needs help: Validator not working with Struts/Velocity
I'm fairly new to Struts, and have been trying to get my simple
application to work - using Struts 1.1, Velocity 1.3.1, Velocity
Tools 1.1-rc1, and Tomcat 4.1.29. The application (such as it is)
works as far as presentation and workflow - but _isn't_ working is
the Validator framework. I've spent the last day mining the web for
help and haven't been able to progress at all...
The validator files _are_ being loaded - I see them in the log
files. And the rules/formset are being parsed - again, I see it in
the log. However, when the form is submitted on the first page
(payment.vm) and it goes to the second...no validation takes place.
No errors are appearing in either the catalina.out or localhost
log file. I have kicked up the log level to trace and still see
nothing wrong - other than the validation doesn't seem to happen.
Any help or suggestions would be GREATLY appreciated - I'm rather
stuck at the moment. I'm sure its just some silly configuration
or other error...
I'm including all the relevant files inline below.
Thank you very much

Re: Newbie needs help: Validator not working with Struts/Velocity
Posted by "Marino A. Jonsson" <ma...@hotmail.com>.
I see nothing wrong - the actions look fine and #errorMarkup() should take
care of displaying any form errors. Did you model this after the validator
example in the velstruts appliction that comes with Velocity Tools 1.1-rc1?
cheers,

Re: Newbie needs help: Validator not working with Struts/Velocity
Posted by Niall Pemberton <ni...@blueyonder.co.uk>.
You say "No errors are appearing in either the catalina.out or localhost log
file" - I don't think validator logs anything to those places and saying
that makes me think "what are you expecting to happen when validation
fails".
The normal course of events when validation fails is struts saves an
ActionErrors object in the request under a certain key
(org.apache.struts.action.ERROR) and forwards to the "input" parameter
defined for your action.
If you were using jsps you would then probably use the <html:errors> tag
which processes the stored ActionErrors and displays the error messages to
the user - I don't know velocity but presumably you could do something
similar.
Looking at your struts-config.xml, its your /Processing action which you are
expecting to validate - its input attribute is "/Payment.do" - this action
forwards to your velocity stuff "/payment.vm" - is there anything in
"/payment.vm" which displays the ActionErrors? To be honest your action
looks to be configured the wrong way round, I would have expected:
<action path="/Processing"
type="org.apache.struts.actions.ForwardAction"
name="paymentForm"
input="/processing.vm"
validate="true"
parameter="/Payment.do"/>
How about setting up a "validation errors page" in velocity and changing
your input parameter - that way if you get an validation error you should
see a different page. Something like...
<action path="/Processing"
type="org.apache.struts.actions.ForwardAction"
name="paymentForm"
input="/paymentErrors.vm"
validate="true"
parameter="/Payment.do"/>
