No 'Access-Control-Allow-Origin' header is present on the requested resource in JBoss EAP 6

Solution Unverified - Updated -

Issue

  • We have an ajax application and it have a request redirecting to another domain, the browser say:
"XMLHttpRequest cannot load: "URL". No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://appcore.cosanitas.com' is therefore not allowed access"

We need to enable cross-domain for this application or for its instance. How we can configure it in JBoss?
