Plus it could do with a little more "meat" than just demonstrating
some edge cases that cannot be supported with the JAXB/JSON integration.
BTW i also used Jackson/JAX-RS recently with a bit of Scala as i did
not want to introduce JAXB annotations:
http://blogs.sun.com/sandoz/entry/simple_long_polling_in_scala
I had to do a little "code gymnastics" due do a bug (not in Jackson/
JAX-RS) and because Jackson does not (yet???) understand Scala types
such as List. IMHO having Scala-based support for Jackson would be
really nice.
