I am a bit stuck trying to make a call to my Java RESTFUL API with jQuery.
Debugging I have found both OPTIONS and GET method are called but when GET method finishes in the server, json is not retrieved and an error raises in the broswer.
OPTIONS REQUEST
OPTIONS /PTGServices/ptgapi/v1/clients/1/ngos HTTP/1.1
Host: localhost:8080
Connection: keep-alive
Cache-Control: max-age=0
Access-Control-Request-Method: GET

GET REQUEST
Accept:*/*

X-custom-1:value1
X-custom-2:value2
In Chrome, this GET request shows an orange warning indicating : 'CAUTION: provisional headers are shown' and there are no GET response
In Firefox, there are no warning but the response is empty too.
After some researching, I found this post indicating both responses (OPTIONS and GET) must have the Allow-Control headers, so I put it but still not work...

Some idea?
Thanks!
Update 1:
I have found it can be an Spring Integration "issue", since when I retrieve Access-Allow-* headers, it is being mapping into "X-Access-Allow-*"
