How do I marshal nested lists as JSON using Jersey? I get an array of nulls or an array of one-element dictionaries containing an array.

I'm working on a project which uses Jersey to convert objects to JSON. I'd like to be able to write out nested lists, like so: {"data":[["one", "two", "three"], ["a", "b", "c"]]} The object I'd like to convert first represented data as a <LinkedList<LinkedList<String>>>, and I figured Jersey would just do the right thing. The above wa...

When declaring an associative array, how do you handle the indentation of the elements of the array? I've seen a number of different styles (PHP syntax, since that's what I've been in lately).
