I'm a bit partial to option 2 since that is how we do it in JS,  however; there is a pattern in node where there is one callback that is passed an error argument( if available ).  something like this gist

https://gist.github.com/lholmquist/7023904

although either way, we are determining what is an error

So I started to look more closely to this, and I'm wondering how we want the Callback to be. I see 2 options that are described here : https://gist.github.com/sebastienblanc/7023151

Basically, version 1 has a 'completed' method which will be invoked no matter which http status code is returned, the developer has than to implement it's own logic of handling the status. The 'failure' method will be invoked  in case of an exception is thrown (IOException for instance)

Version 2 has a 'onSuccess' method which handles the 2xx response codes and a 'onError' which handles 4xx, 5xx codes or even if an exception has occurred.

Do you have any preference or even an alternative solution ?

I was speaking about the latter.
