Newbie question - deploy my BIRT project to WAR

Hello all,
I have started working with BIRT.
We got a prepared project with library, DataSets, DataSources, Reports and more.
I am using the newest version 2.3 with the full package eclipse.

We want to get this project, create a WAR and put it in our JBoss server.
After searching, looking and re looking, we could not find a decent explanation of how to do it.
We looked in the deployment section, downloaded the WAR structure. But it is not mentioned which files / classes we should put there and where.

Is there a better place that explains this issue?
Thansk
