Hi Viral, Your Tutorial is Simply Awesome. Even to say i started likely Struts after visiting your site.
Thx. But When i executed the above code in the customer screen no validation is happening. Even if i leave all fields empty and click add customer, its adding. I had all names same as like how u gave in ur example…

@Lansana – The 404 error might be coming due to issues in dependencies. Check the server logs. You might have some other exceptions there.

I have tried the tutorials, but I am having difficulties. Each time I run the HelloWorld example, I have a 404 error in the browser. I have used the latest version of tomcat, and Struts, is it because of this or I’d have to use the older versions that were used by you?

Great tutorial so far. I have one problem – when I add ‘validate=”true”‘ to enable client-side validation, I get the following error message in my browser:

validateForm_customer is not defined

I inspected the HTML source and the source of the included validation.js and utils.js files, and there’s definitely no trace of that function. Is there something else that needs to be done to enable JS generation? I’m using Struts 2.2.3 and Tomcat 6.0.32.

Thanks!
