Correct, it's not complete.  There is no OpenSRF translator or gateway class
in Java.  However, it does implement most of the basics for OpenSRF object
handling and serialization.

[snip...]

It's not necessary to build the JSON by hand.  You can create an
org.opensrf.Message object, pass in a Java Map or Java Array (or string,
number, boolean, etc.  See [1] for options) as the payload object.  Then,
simply calling toString() on the Message will generate the JSON for you.
