ActionErrors.validate()
Hi all,
I just started reading a book about Struts, and are now learning about Error
Handling. To validate the input of the user in the forum, you need to write
your own implementation of org.apache.struts.action.ActionErrors. The class
ActionErrors has its own method validate. This method I can change to suite
my wishes. The only problem is, how is this method called. I can not find
any direct call of MyActionErrorsImplementation.validate(myMap, myRequest)
in my code.
Am I correct in assuming validation is done automatically by the application
server? And if so, how? Or am I thinking in the wrong direction? If so, what
do I read?
TIA,
Abel

Additionally when posting to the struts list, definitely mention what
version you are working with. A cursory look at the struts website
shows version 1.3.x is significantly different from version 2.0.x.
I will say the class you are trying to extend should probably be
ActionForm if using Struts 1.3.x instead of ActionErrors. ActionErrors
is really a collection of messages returned from the validate() method
of an ActionForm instance. If nothing else, the docs and articles
available on the Struts website should help you out a lot.

The Struts mailing list is probably a better place to start.
