Hi Paul,
This is a very common practice so you can use the service from a
<script> include within a web page. I am actually surprised that JAX-
RS doesn't support JSON callbacks out of the box because it is such a
widespread practice. For instance, all Yahoo web service APIs support
this as one of the result formats. It is generally referred to as
JSONP. There should likely be a provider that supports it:

http://developer.yahoo.com/common/json.html#callbackparam
