You need to make sure you have the Community Commons module installed from the Marketplace. That will give you the GetApplicationUrl Java Action.
You should have a module called AnimalRegister that has a constant called environment. This appears to be missing so you will need to recreate it.
It also looks like you should have a Layouts module with a Layout called NDGFullScreen that is missing.
Hope this helps, good luck!
Robert do you have also a idea about my next error? :)=
