1. No there is not; obviously you can use an existing module such as AdminType or so and work from that. If you like to create a template AdminFoo, maybe to go in the hello-world example, that would be great!

2. We would recommend all people who do OTRS customizations to use OPM packages for that. It just makes it really easy to separate modifications from the system, and it makes Dev > Test > Production moves easy.
I guess you'd want to look at creating an .sopm file for your package, which is described here: [http://doc.otrs.org/developer/2.4/en/html/c1284.html]

You can then build OTRS packages by using bin/opm.pl -a build -p /path/to/Package-1.0.0.sopm

Hope this helps,

Great stuff, thanks! Figured it was something like that, but my xml file
wasn't correct/complete. Couple more questions if you don't mind:

1. Now I'd like to fill the bottom window with [Foo Managment] when
clicked, is there a template Kernel/Modules/AdminFoo.pm for that?

2. Noticed that this kind of installation stuff is done automatically
when loading from the package manager. Is this interface definition for
OPM-files explained anywhere?

mvg, Kiffin

Hi Kiffin,

I'd recommend you to just take a look at existing configuration options.

In your case, you could create a file called Foo.xml with your
configuration options. This is a nice way to separate them from the
'canned' configuration options.

This file would provide an entry for the AdminFoo module. Just place it
in Kernel/Config/Files, go to Admin > SysConfig in the interface (this
will trigger the file rebuild) and the link will appear in the Admin
section, in this case on the bottom of the third row.

<?xml version="1.0" encoding="iso-8859-1" ?>
<otrs_config version="1.0" init="Application">
    <ConfigItem Name="Frontend::Module###AdminFoo" Required="0" Valid="1">

AdminFoo configuration object in the admin area.</Description>

Hope this helps,
