Does the DatatypeHint with bridgedTo can meet your requirements? For example: ' public @DataTypeHint( value = "RAW", bridgedTo = JSONObject .class, rawSerializer = JSONObject Serializer.class) JSONObject eval(String str) { return JSONObject .parse(str); } ' You may need to provide a class like JSONObject Serializer that extends TypeSerializerSingleton.

Any help would be appreciated.
