Question

Id like to represent a Class object as JSON. For example, if I have the class defintions as follows:

public class MyClass {
    String myName;
    int myAge;
    MyOtherClass other;
}

public class MyOtherClass {
    double myDouble;
}

I’d like to get the following nested JSON from a Class object of type MyClass:

{
   myName: String,
   myAge: int,
   other: {
      myDouble: double;
   }
}

EDIT:

I don’t want to serialize instances of these classes, I understand how to do that with GSON. I want to serialize the structure of the class itself, so that given a proprietary class Object I can generate JSON that breaks down the fields of the class recursively into standard objects like String, Double, etc.

I would recommend to use Jackson.
You can also take a look at the JSonObjectSerializer class based on Jackson which can be found at oVirt under engine/backend/manager/module/utils (you can git clone the code) and see how we used Jackson there.
