Re: [json-lib-user] Default values when converting from Java beans to JSON objects

[Florian S. <flo...@gm...>]

Hi Andres,

Here's a reply to myself :-) that might provide some sort
of solution to the previous problem (although it is as elegant
as an elephant)

We can create a Map<Object, Object> that will contain
all the names of the fields from the Java bean that we want
to convert into a JSONObject associated to their values.

Instead of converting the Java bean into a JSONObject
we can convert the map. In fact both

JSONObject.fromBean( map ) and
JSONObject.fromMap( map )

seem to work as expected. I am not sure whether there
are any subtle complications with this approach, but it seems
to solve my problem (at least at the moment...)

Thanks agin,
Florian
