I've written a small program to call a REST Web Service written in Jersey.
The service works, and responds with a JSONObject as expected.
But the client keeps throwing warnings and exceptions.

Here's the code for the client.
ClientConfig config = new DefaultClientConfig();
myClient = Client.create(config);
WebResource resource =
myClient.resource("
http://portal-dev2.sgns.net:8181/Case/create");
MultivaluedMap map = new MultivaluedMapImpl();
map.add("Format", "json");
map.add("IncidentID", " HD0000001042502");
map.add("CreateDate", " 2009-07-01 16:47");
resource = resource.queryParams(map);
/* resource.getURI().toString() returns

&Format=json&CreateDate=2009-07-01+16:47 which works.*/
/* Line 199 */
Object object =
resource.accept(MediaType.APPLICATION_JSON_TYPE).get(ClientResponse.class);
Can anyone please shed some light as to what's causing this? I've read
pretty much everything I can get my hands on, but I'm at a loss.
Thanks,
Scott
