Problem in win32-service ... or ... what?

I am trying to build an windows service ( WIN XP SP-2) using the
Win32-service package for ruby.

This service is supposed to pull some stock data from yahoo site
every minute and print to screen.

For this objective to be accomplished i have the following three files

1> yahootickerpull.rb

This has a class Yahooticker and a method called refresh.

2> datasrc_ctl.rb

This has code for controlling the service like
install,start,stop,delete etc… Here i utilize the win32/service

3>yahootickerservice.rb

Here i require the yahootickerpull and win32/service … and override
the “Daemon” class onto “YDaemon” class .
In the “service_init” method i create a Yahooticker object … and in
the service_main method i call the refresh method of this object.

This is the blue print.

problem is i get an error:

C:\mooney.com\historicalqoute\yahooticker>ruby datasrc_ctl.rb start
VERSION: 0.5.2
datasrc_ctl.rb:61:in `start’: The service did not respond to the start
or control
request in a timely fashion. (Win32::ServiceError)
from datasrc_ctl.rb:61

==================================

I suspected the win32/service … but the example code that comes
with the package tdaemon.rb and tdaemon_ctl.rb… works perfectly

So i suppose i am doing some fundamental mistakes…

Is there anything in the log?

Also, be sure to put your require’s within the begin block. The last
time someone reported a similar problem it turned out they were
require’ing a custom library that wasn’t in their $LOAD_PATH. I wonder
if the same thing is happening with yahootickerpull.rb.

Thanks for your reply

I did it as you suggested … the yahootickerservice.rb now has the
require statements in begin block.

so now i get the log file also that shows exactly what you guessed

…“Daemon failure: no such file to load – yahootickerpull”

so any lead … how do i include require yahootickerpull correctly
?

cheers

You either install yahootickerpull.rb in ruby sitelibdir, or you modify
$LOAD_PATH to point to wherever your yahootickerpull.rb file lives.
