WEBrick OS X StartupItem?

Is it possible to create a Startup Item for WEBrick? My startup item, 
named swu, works fine when I run it from the command line, just not 
when the computer is starting up. I''m wondering if some resources are 
missing for ruby to load at this point... or something. Here''s output 
from /var/log/system.log... Any suggestions would be appreciated.

Aug 18 21:18:58 localhost SystemStarter: Starting SWU Rails App from 
script
Aug 18 21:19:06 localhost SystemStarter: swu (132) did not complete

What are the permissions on /Users/salestraining/rails/swu/ ? Does that
directory exist?

Is ruby in the path at startup?  Try replacing ruby script/server with
/usr/bin/ruby script/server, or the OS X equivalent. 

What does it say in log/startupitem.log? Does that file exist? Is the
timestamp the same as the last startup time? Is that directory writable?

Is there any additional error messages written to the console at
startup?

Re: WEBrick OS X StartupItem?

Many thanks for the troubleshooting ideas. I answered all your  
questions below. Since then it''s started working all of a sudden, which
is annoying since I didn''t discover exactly why it was failing before.
I''m slightly concerned that it might *stop* working at some point in  
the future just as mysteriously as it *started* working. Maybe it was  
some permissions problem that I inadvertently changed while messing  
around with it. Oh well. Here''s the final script...

#!/bin/sh

. /etc/rc.common

StartService ()
{
    ConsoleMessage "Starting SWU Rails App from script"
    cd /Users/salestraining/rails/swu/
    /usr/bin/ruby script/server -d -e production 2> log/startupitem.log
}

RunService "$1"

I tried this but I still get the error in system.log, unfortunately.

trg-admin:/Users/salestraining/rails/swu/log root# cat startupitem.log
=> Rails application started on http://0.0.0.0:3000

It''s funny that it''s getting this far, but still is failing.

Yes and yes.

Not any that popped out at me, but there may be. Here''s a better sample
of the log at /var/log/system.log...

Joe,

The log file message: "Rails application started on http://0.0.0.0:3000 
" indicates that your script is successfully starting webrick, but there 
is a discrepancy in the logging. That log entry is from stdout which is 
what the previous version of the script collected, but the latest script 
shows you logging stderr.

Try capturing everything:

/usr/bin/ruby script/server -d -e production 1> log/startupitem.log 2> 
log/startuperr.log

You''ll want this output sooner or later anyway, I think, although I 
don''t have time to track down exactly how webrick is logging errors.
You
should see any errors there.
