The solution until the webservice deliver that headers is:

Solution 1:

1. Put the webservice behind a remote or local proxy
2. Apply some a filter (decorator) for each response with the CORS headers
(in the proxy) in order to trick the browser

Solution 2:

Some time ago I tested it with Chrome (disabling security) and it worked
for me

Solution 3 (really dirty, but works):

Embedded Flash Proxy
