I access the class before displaying the form because I want the dropdown option in the form to display the appropriate value as I instantiate it in action class. But it turns out, it will return "input" and I must handle it.

问题 I have what I'd think is a common issue but an entire day of googling hasn't turned up anything useful. I have a form with a checkbox and a textfield. I'd like to do a regex validation of the textfield, but only if the checkbox is selected.

So now I have a result with input name in my action without understanding well how it works and why. My action returns a

问题 I'm trying to make a login page in Struts. The idea is to validate if the user exists, etc, and then if there is an error, return to the login page with the errors in red (the typical login or any form page validation).
