[Glass] Debugging an app with Jade

[Lyn Headley]

I got a helpful hint from Sebastian Heidbrink, which led me to discover
the ControllingSeaside30Gems wiki page. However, I only seem to be able to
launch fastcgi gems when I want to launch Swazoo gems. If I evaluate the
following:

"Specify Swazoo for runSeasideGems30 and start 1 vm listening on port 8383"
WAGemStoneRunSeasideGems default
        name: 'Swazoo';
        adaptorClass: WAGsSwazooAdaptor;
        ports: #(8383).

WAGemStoneRunSeasideGems startGems.   "start gems"

I can see a couple of topaz processes running:


laheadle  3192  0.0  1.2 210664  6028 ?        S    05:56   0:00
/opt/gemstone/product/bin/topaz -l -e
/opt/gemstone/product/seaside/etc/seaside30.conf
laheadle  3194  0.0  1.7 692900  8900 ?        S    05:56   0:00
/opt/gemstone/product/bin/topaz -l -e
/opt/gemstone/product/seaside/etc/maintenance30.conf


So far, so good. But I can't load http://myhost:8383 in my web browser, and
when I telnet to port 8383, I am told:

0Incorrect FCGI version. Expected: 1 Received: 71Connection closed by
foreign host.
