You can also use Genson to add class name of your objects to the outputed json, just do:

Genson genson = new Genson.Builder().setWithClassMetadata(true).create();
String json = genson.serialize(yourNode);

The nice thing is that it enables you to deserialize back to those concrete types. See the wiki for more details.
