Antonio,
main() methods are not managed by Furnace, hence why @Inject does not work. You need to fech these services from the AddonRegistry:
Eg:
furnace.getAddonRegistry(ResourceFactory.class).get()

If I'm right, Roaster is nice to add bits and pieces of Java here and there, but it's better to use Templates when there is a lot of code, and mix templating and Roaster for better code customization.
