I've downloaded NetBeans 6.5.1 and followed the tutorial from the following link:
When I pressed F6 to run the project, I was prompted the following:
Cannot find the Web Pages folder "C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\HelloWeb".
Open the project properties and in the Sources category browse the correct Web Pages folder.
The whole project was deleted when I was prompted the above message. I needed to follow the tutorial once more. When I run the project again, the same happened.
