Questions on Struts

[Mike Yu]

Hi,

I am new to Struts. I have some questions that may be simple to you.
(1) How do you validate user input in Struts?
(2) What uniquely identifies an Action element, for example, name, path or something else?
(3) Does the reset in ActionForm set properties to the initial values or to the request parameters?

You can validate in the validate method and return an error if the data is invalid.

The reset method should be used to reset checkboxes only as their state is only forwarded on a submit if they are checked.

You should initialise your stuff within action classes, see my posting here:

Mike,
2) The path is what needs to be unique. You can the same action class servicing several types of requests by changing the form bean or forward.
