Error when running things through the public directory

Hi,

I'm running the latest version of Ruby on Rails on Fedora Core 6
Linux. I created the simple "hello world" application found on the
RoR site (http://wiki.rubyonrails.org/rails/pages/Tutorial). B/c of
the hosting company I'm using, I would like to be able to run

http://mydomain.com/myapp/public/hello/world

but when I try entering this URL on my dev server, I get this error:

"We're sorry, but something went wrong.

We've been notified about this issue and we'll take a look at it
shortly."

What does it mean and how can I troubleshoot?

Thanks, - Dave

The actual errors will appear in the log files, log/development.log
when running in development mode for example.

Thanks, but there is nothing in the logs. I am running under the
Apache 2 web server. Is there something I should do there? Since
the .htaccess is routing everythinng to dispatch.cgi, I didn't think I
had to, but I'm a beginner at this stuff. - Dave

You also checked ALL the logs (production too), right? That error is a
RoR generated error, meaning that RoR will have logged something
somewhere.

RoR is being activated correctly, so it's something in the program
itself that isn't working... and without logs it's really really hard
to guess what that might be.

Ok, I reset the logs, visited the page above and here is what is in
the development.log file. Not sure what it all means:
