java ee - Best practice of parsing RESTful WebService response with Rails -

I am developing a JAX-RS application and it's working fine. Now, I want to develop a web service customer application using Rail. And my question is: Is the best way to parse the response of a resident web service in the railways?

Depending on what the service is returning, I would say that you have to do different gems Can be used. Recently, I am using an ASP to automatically receive and parse the call response.

Once I get all the data then I map it to a model so that it is easier to manipulate later. The way you do this mapping, it will really depend on the type you will get.
