[Json-rpc-java] "better" tutorial?

[DGraham at EvergreenInvestments.com]

Hi,

I'm _very_ interested in using this library to facilitate my move to 
AJAX....however, it's not obvious to me how a complex object will be 
returned, and how I would use it.   It's easy to see how the canonical 
"Hello, World" example works, but what if I want to return a collection of 
JSON objects and then iterate over those objects?   Is there a richer 
example?

Thanks,
Dennis
