Problems creating a web application

[saggiatorius]

Hi, I tried to create a web application with SP2007, but when I try to access the URL the "Internet Explorer cannot display the webpage" page appears. And when I try to browse the corresponding website from IIS, the "Server Error in '/' Application" page appears.

I created the webapplication and the site collection from the central admin, and then I recycled the application pool.

What's wrong?

Thanks
