Make sure you set the "input" attribute in the <action> element to point to your error page. When the validate method returns a non-empty ActionErrors object, Struts will forward the request to the location specified by the "input" attribute. A question for you. If you are using Struts 1.1, have you considered using the validation plugin and specifying the validation requirements (including regular expressions) in the validation.xml file (as opposed to programatically doing it)? By doing this, you would be moving the validation requirements out of your code which makes it easier to maintain. --- Outgoing mail is certified Virus Free.
