Hi Valerio, Welcome to the community! Apparently there is some issue with the helloworld module mentioned in the documentation, the very same issue was reported here on the dev list a while ago. If you would like to see an example of how a module should work, you can check out any of the other modules on http://source.otrs.org For your daily use it is fine if you just put the files in the otrs dirs, for development it's much easier and cleaner to put them in a separate dir and symlink them with the module-tools script. Good luck with development, if you have questions, just ask, and if you've developed something cool it would be nice if you'd share. Michiel "valerio cacciatore" wrote:

Hello Community, I'm new with OTRS but I find it great. I was trying to setup my first module but I have some problems.

It is not clear to me if I have to create new directories for the developed modules or I can use the dir already present. Can someone give me a first help? Moreover I tried to create the files in already existing directories and I was successfully to have the new module in my control board but I have this error code: Software error:

Can't call method "FatalError" on an undefined value at ../..//Kernel/Modules/AgentHelloWorld.pm line 29.

For help, please send mail to the webmaster (webmaster@localhost), giving this error message and the time and date of the error.

Thanks for support,
