Struts 2 question about validation and forwarding
Hi,
If request validation fails, how can I forward the user to a different page
than that from which they came? The scenario is that an external web site
is going to invoke our site with something like
"/ourForm.do?param1=xxx¶m2=yyyy" and if their parameters are not valid,
we want to forward them to another page on our site.
Thanks for your help, - Dave

That's Struts 1, not Struts 2.
You may need to call validation manually (not a big deal) and return a
different ActionForward on failure.
FWIW, that's what I almost *always* did in S1: I had a base action class
that went to input on a GET, validated on a POST, and could be set up to
do various things on validation failure. YMMV.

Hi,
If you use Eclipse, you can see Akrogen <http://akrogen.sourceforge.net/>which
is Eclipse plugin to describe your wizard with XML (XUL) and Javascript and
link it to a template (XSL, Freemarker, Velocity...)
Akrogen works wit catalog (folder which contains, XUL wiizard, templates..).
You can find catalog for Struts1.x at
http://akrogen.sourceforge.net/struts-catalog/struts1x.html
But it's easy to write your own catalog to generate what you want.

You can use Java APT:

We use it for struts-annotations (internal tool to generate TLD files for tags):

Hi, Im searching for tools that allows to generate some struts resources,
like validation and app resources. I was looking around and I found the
xDoclet annotations for to generate struts code, but my database is really
so big, not so easy going to all the POJOs for to do that. Any other way,
please?
I was trying also to find ways to generate the POJOs with xDoclet
annotations because anyway hibernate contains max-lenght and no-null
values...

IIRC execute isn't executed on a validation failure; that's what the
"input" attribute is for, so S1 knows what to do via config w/o
programmer intervention.
If you're working outside of the framework defaults then you'll probably
need to do something manually, although if this is an application-wide
requirement something could probably be done with a custom request
processor.

Re: Struts 2 question about validation and forwarding
Posted by laredotornado <la...@gmail.com>.
Hi,
I only want to forward if validation fails -- i.e. don't need to run the
"execute" method. But I don't know how to set that up in my
struts-config.xml file (or some other file if that's what's needed). How do
I do that?
Or is the only way to do this is as David Newton suggested -- moving
validation into my execute method and forwarding appropriately.
Thanks, - Dave

Re: Struts 2 question about validation and forwarding
Posted by Burton Rhodes <bu...@gmail.com>.
Exactly. If validation fails, execute will not be called by design.
Since all you want to do is forward, you shouldn't need to run your
execute method. The forwarding will take place in your struts.xml file
as previously suggested.
If you need to execute code regardless of the validation, look into
the prepare method.

Re: Struts 2 question about validation and forwarding

But it seems like the "ActionErrors validate" method from my ActionForm class
is called, fails, and my execute handler is not called. Is there a way in
the struts-config.xml file that I can set up a foward upon validation
failure?
This is what my struts action is currently ...
<action path="/hhFlow"
type="com.myco.regui.struts.accounts.AccountsAction"
scope="request"
name="REAccountLookUpBean"
validate="true">
</action>

Just have the result of the input() method return them to a different page
under that condition.
