title: Java: serialize TreeModel, TableModel to JSON, and vice versa?
body: <p>On the client side, a user specified input creates a unique TreeModel and TableModel.</p>
  
  <p>This needs to be serialized to JSON for storage on MongoDB (stores JSON document directly).</p>
  
  <p>The JSON needs to be parsed back into a TreeModel or TableModel which will be rendered again on the client side software.</p>
  
  <p>Any library or existing codes which can faciliate this?</p>
