Hey Guys,

I recently moved my RoR project to another puter and when I attempted to  
start up Mongrel (or Webrick) I got the following message on the Windoze  
console…

After about an hour of scratching my head I remembered that my project  
needed the sparklines gem. A quick question for the gurus… aside from  
relying on my faulty memory, where can I look for diagnostic messages in  
the future? The log/server.log file was empty…

Sonny.

=================================  
=\> Booting Mongrel (use ‘script/server webrick’ to force WEBrick)  
=\> Rails application starting on [http://0.0.0.0:3000](http://0.0.0.0:3000)  
=\> Call with -d to detach  
=\> Ctrl-C to shutdown server  
\*\* Starting Mongrel listening at 0.0.0.0:3000  
\*\* Starting Rails with development environment…
