Problems with mongrel_service and used account

Server Mongrel
1

Hi everybody,

I try to use in a rails application that is installed with
mongrel_service
on windows the win32ole API to access Outlook appointments. This works
well when started from the command line, but does not work when started
as
a service.

What should I check in which order to trap down the error?

Bye

Hello Markus,

Services run without privileges for certain things, like create
objects and such.

Since you’re executing from the command line and work, means that your
user has access to these OLE objects.

There are two options:

  1. Configure the service to run under the same user account (that can
    be done from the services management interface)

  2. Determine the issue using psexec.

Try to lower the privileges of the prompt and execute the exact same
command line.

The tools you need are psexec, as I mentioned here:

http://rubyforge.org/pipermail/mongrel-users/2007-February/003006.html

See that thread for details.

Please also include in your reply information about your OS (32bits or
64bits), versions of Ruby and the gems installed too.

There is a known issue with 64bits Windows that was solved in latest
gem release, just in case.

Cheers,

I just tried that. See my question on Stackoverflow
(Error when reading Outlook calendar from Rails application when started as a mongrel_service - Stack Overflow)
and the hint of Mr. Doggen that this may not work with Outlook.

I have tested it again with the correct user account and it did not work
either. So I found the workaround:

Start a small script like

ruby script\runner ‘AppointmentController.new.refresh_no_redirect’

I did not tried that, thank’s anyway for the recommendation.

Well, I don’t think that they matter here. I use Windows XP (32bit),
ruby
1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]

There is a known issue with 64bits Windows that was solved in latest
gem release, just in case.

Cheers,

Thank’s a lot for your hints.
