Re: [Resteasy-users] question about CORS

[Bill B. <bb...@re...>]

There is no good way to implement this in 2.3.x.  You would have to 
write a resource class to handle all preflight OPTIONS requests. 
Depending on how you want to validate origins, you'd have to write a 
PreProcessInterceptor and PostProcessInterceptor and @Context inject a 
HttpResponse or HttpRequest respectively.

FYI, 2.3.x is retired in the community and support and updates are only 
available by subscription.  3.0.x has been out for a year and can be 
installed on top of AS7 or EAP 6.x
