[Building Sakai] JSON

[Charles Severance]

Mark,

I started using org.json.simple because it was really simple - and if all you have to do is tear apart a bit of incoming JSON - it is a nice way to go because it is quick and easy.

But as soon as things get a little more complex (i.e. like building LTI 2) and having to construct outgoing JSON that meets other folks requirements and not doing some *nasty* code - I quickly switched to Jackson (thanks to Aaron's earlier advice to me when I asked the same question) - and I *love* it.  And you know how lazy I am and how quick I am to use sprintf when faced with a complex data modeling problem :)

It is not quite as quick and dirty as org.json.simple - but it is pretty easy to use (thanks to awesome code generators and nice use of annotations) - so I highly recommend it.   For LTI 2.0, I would *still* be debugging it if I had not switched to Jackson.  And in particular as LTI 2.0 makes a few subtle changes - Jackson will very much be my friend.   Te generated code is so simple and clean that if the data model gets tweaked - you usually can easily tweak the generated code rather than generating it all from scratch and shoving it back into your code.
