I have multiple Java bean classes that are associated to each other (JSON Array + JSON Object) since they have a nested structure. There are about 10 classes. I had created these classes out of a JSON data which I don't have access to right now. So, now, what I'm looking forward is to create a dummy JSON out of those classes. Using GSON, I tried converting one of these Bean classes however, I got an empty result. Here is one of the beans called Attachment.java.

Attachment.java
