I see now I misunderstood the complete functionality of "JSONP", no
XMLHttpRequest is made at all, and as a result it's not possible to
control HTTP headers. In my case a script like:
<script type="text/javascript" src="http://localhost:9998/search/jonas?
callback=jsonp1263842210822 "></script>
is injected and and loaded by the browser. Is there a way to check
whether this is loaded at all? I guess the browser will not evaluate
it if the server returns an error-code.
As far as I can see an $.ajax( call which uses JSONP functionality
will never call the error function. This would mean that the option to
use would be to implement custom error handling at the service with
messages and HTTP status code 200.
