changing the struts validate return page

[Siripa Siangklom]

Hi
I am trying to change the page that struts redirects to upon a
validate error.
Normaly you are returned to the source page with errors to show,
However I want to be redirected to a page of my decision.
Does anyone have a clue?

I'm not very sure what the recommended practice is right now but prior to version 1.1, you could invoke ActionMapping.setInput(). Then in the pre-release 1.1, that method threw an IllegalStateException(?) or something like that if any attempt was made to modify the input attribute of an ActionMapping that had already been initialized by Struts from the configuration file, which would be the normal case. Looking at the final release of the JavaDocs however, the exception declaration seems to be gone and looks like setInput() has been "reinstated" as the way to make the return form more dynamic.
(If anyone knows otherwise, please correct me )

In struts-config locate your corresponding action tag. You can add an attribute to this tag of input="myErrorPage.jsp"
I don't know if a worse name could have been created for this attribute but it works. Whenever the validate method of your form doesn't like something your user will be sent the page you specify as input.
