[Catalyst] Apache/mod_perl 2.0 deep documentation and troubleshooting

[Xavier Robin]

Hello,

I have a Catalyst application "MIAPE" working as standalone server. Now I 
would like to use it in mod_perl (perl 5.8.5, Apache 2.0.52, mod_perl 2.0.3 
on a 64 bit machine).
So I took the documentation 
(http://search.cpan.org/~agrundma/Catalyst-Engine-Apache-1.07/lib/Catalyst/Engine/Apache2/MP20.pm) 
and I added the following at the end of httpd.conf :

    PerlSwitches -I/home/xrobin/MIAPE/lib
    PerlModule MIAPE
    <VirtualHost>
        ServerName    miapegeldb.isb-sib.ch
        DocumentRoot  /home/xrobin/MIAPE/root
        <Location />
            SetHandler          modperl
            PerlResponseHandler MIAPE
        </Location>
    </VirtualHost>

Apache restarted successfully. But the application doesn't work.

Unfortunately, there is no error message in the apache error_log file. I don't 
know what I did wrong, nor where the error is (Is the application loaded? Is 
there a network/firewall problem? Etc.). I looked for a more complete 
Catalyst/mod_perl 2 documentation, and in the list archive, but I couldn't 
find anything.

Do someone know what I did wrong, or where I could find some documentation for 
debugging?

Thank you,
Xavier
