This is a simple implementation in Java for the server side of [examples/crudl.sadl](https://github.com/boynton/sadl/blob/master/examples/crudl.sadl). To build and run the server:
$ make
Then you can test it. This session uses a "json" utility to pretty-print the results. To get it:
$ go get github.com/boynton/hacks/json
Or you can just omit the | json for each example and parse the one-line JSON yourself.
Here is an example session against the server launched as above. Note the test of conditional get based on modified time.
