making cross domains call to indesignserver using jsonp?

Greetings!

I'm currently trying to call the following url: http://localhost:12345/service?wsdl

from: http://localhost/cvapp/

offcourse, I get the following errors:

OPTIONS http://localhost:12345/service?wsdl 405 (Method Not Allowed)

XMLHttpRequest cannot load http://localhost:12345/service?wsdl. Origin http://localhost is not allowed by Access-Control-Allow-Origin.

Is there any way I can make a call to my indesignserver soap instance using a jsonp request?

Thanks!

Regards

Mario
