Hi, Do you want to have the following methods support JSON value (i.e. the value is a JSON string)?
> void addEntry(String key, String value) throws DuplicateEntryException; > void updateEntry(String key, String value) throws EntryNotFoundException; We have the JSON data binding. Maybe you can use org.json.JSONObject as the argument type so that the JSON data binding can introspect them as the JSON data binding.
