Building a login application (In Netbeans 731) which basically ensures non blank values for username and pw. The application runs fine except the validation doesn't work, so even if the user enters blank values they are taken to the Thanks.jsp page. After trying to build it as a Netbeans web app, I have rebuilt this application using Maven, with the following directory structure:
The generated war file is:

When I built this application manually (with Maven) it gave a stack trace due to wrong version of DTD tags. I no longer get this error after building the application using Maven.
When running this application I call the Required1.action. Even if I do not enter a password it skips straight to Action2 and the validation interceptor (RequiredTestAction-validation.xml) does not seem to be working.
