Having looked at ServiceDelegateImpl, he tries:
InputStream is = wsdlURL.openStream ();
where wsdlURL is nonzero URL. This means that the problem is openStream(). I expect the problem will be with the https root certificate; I can imagine that JBoss has its own supply of valid root certificates somewhere and that your root is missing there.
What I would do to verify this is to deploy the service on an HTTP server and make wsdlURL a URL http. If this works, this is the SSL level.
If this is the SSL level, try manually adding keyStore, specifying it on the command line, as in the answer to this SO question .
