Change Input parameter at run time
Greetings
I have an application i have inherited. There is a situation where 2
jsp's submit to the same action with the same form bean. In the
validation function inside the form bean if there is one type of error I
want to set the input parameter to /jsp1.jsp and put an ActionError on
the ActionErrors. If there is an error of type 2 I want to set the
input parameter to /jsp2.jsp and put an error on the ActionsErrors.
The just of all this is: the input parameter is set in struts-config.xml
and it validation fails it goes back to this jsp for the user to fix
it. I need to change the input jsp page dynamically from inside the
form bean.
Please help
thanks
troy

Frank's way is simple, declarative and it works. You can also try the
one that I replied with two days ago:

I suggest that instead of hacking "input" property
you abandon it altogether as well as autovalidation. If you turn
autovalidation off, your action.execute() method will always be
called, so you can call actionform.validate() manually and then make a
decision where to forward.

Not sure if anyone said this already, but... if the validation failures
are mutually exclusive, i.e., type 1 cannot occur when submission was
from page 2, and type 2 cannot occur when submission was from page 1,
then I think all you need to do is create another mapping in
struts-config, both identical except for different input parameters.
Even if the errors are not mutually exclusive, you can interrogate the
incoming request to see which mapping was triggered, and only perform
the validation appropriate to the mapping.

Hi
I am not sure if you can do it easily. Maybe some plubing will be needed.
Anyway
concern validation in Action and then forward or redirect wherever you want.

Oh, and by the way, I suggest that instead of hacking "input" property
you abandon it altogether as well as autovalidation. If you turn

called, so you can call actionform.validate() manually and then make a
decision where to forward. Much cleaner if you ask me.

It is not possible (at least legally). You should create a new
ActionMapping object.
