What version of the engine are you running? I may not have the required
cloud-init support.
Try to run the application in debug mode:
Api api = new Api(
"https://whatever/api",
"user at domain",
"password",
null,
null,
null,
null,
true,
null,
true // <- This is to enable debug mode
);
It will send to the log the actual XML documents sent to the server. We
can use it to see if the request is generated correctly.
It may also happen that cloud-init support isn't working correctly. To
verify this try to use the cloud-init support manually from webadmin.
Does it work from there?

To set the host name you need to add something like this:
Host hostData = new Host();
hostData.setAddress("the.host.name");
cloudData.setHost(hostData);
