How To Maintain Cookies Using CXF
How To Maintain Cookies Using CXF explains about Maintaining Cookies Using CXF
I am showing here, How to do maintain Cookies in CXF framework, this is applicable for both SOAP & RESTFul services
Message message = PhaseInterceptorChain.getCurrentMessage(); HttpServletRequest request = (HttpServletRequest)message.get(AbstractHTTPDestination.HTTP_REQUEST); Cookie[] cookies = request.getCookies();
On this code, we are getting HttpServletRequest and from that we are getting cookies object in CXF
You can see the below example, on which we are storing a value into cookies from client side and retrieving the same, using CXF Framework
Enable Cookies Using CXF
I am going to re-use CXF Restful Tutorial
We are making changes ChangeStudentDetailsImpl class, just adding
PhaseInterceptorChain.getCurrentMessage() and getting HttpServletRequest, so that we can access Cookie object in CXF Framework
