Creating a cookie inside a jax-rs endpoint

I have a jax-rs endpoint. The purpose of the endpoint is to authorize a user. I need to login details inside a cookie. Below I have mentioned the related part of my code.

public Response authorize(@Context HttpServletRequest request) throws URISyntaxException {
     if (authnResult.isAuthenticated()) {
     //TODO create a cookie to maintain login state
                        Cookie authCookie = new Cookie(FrameworkConstants.COMMONAUTH_COOKIE, "test");
                        authCookie.setSecure(true);
                        authCookie.setHttpOnly(false);
                        authCookie.setMaxAge(5 * 60);
}

EDIT:

This is my first time when creating cookies. I followed some tutorials. In these tutorials it has added the created cookie to the response. But inside the endpoint I can't access the response. So how can I create the cookie? Please advice me.

Updated code:

public Response authorize(@Context HttpServletRequest request) throws URISyntaxException {
    NewCookie cookie = new NewCookie("CookieName","CookieValue");
                    Response.ResponseBuilder builder = Response.ok("Cool Stuff");
                    builder.cookie(cookie);
                    Response response=builder.build();
    Cookie[] cookies = request.getCookies();
}

what I need to know is how to access the newly created cookie.

You can create a javax.ws.rs.core.NewCookie. There are a bunch of different constructors, just go through the API docs.

Then you can add cookies through ResponseBuilder#cookie(NewCookie). So for example:

@GET
public Response getCookie() {
    NewCookie cookie = new NewCookie("Name", "Value", "path", "domain",
                                     "comment", 300, true, true);
    ResponseBuilder builder = Response.ok("Cool Stuff");
    builder.cookie(cookie);
    return builder.build();
}

UPDATE (with complete example)

@Path("cookie")
public class CookieResource {
    
    @GET
    public Response getCookie(@CookieParam("A-Cookie") String cookie) {
        Response response = null;
        if (cookie == null) {
            response = Response.ok("A-Cookie: Cookie #1")
                    .cookie(new NewCookie("A-Cookie", "Cookie #1"))
                    .build();
            return response;
        } else {
            String cookieNum = cookie.substring(cookie.indexOf("#") + 1);
            int number = Integer.parseInt(cookieNum);
            number++;
            String updatedCookie = "Cookie #" + number;
            response = Response.ok("A-Cookie: " + updatedCookie)
                    .cookie(new NewCookie("A-Cookie", updatedCookie))
                    .build();
            return response;
        }
    }
}

After 38 requests, you can see the result. I used a Firefox plugin Firebug. You can see the sent cookie #37, and returned cookie #38

If you need help trying to access the cookie from the client (as suggested in your comment), that may be suitable for another question on SO. Maybe off topic for this discussion, as it will rely on another technology. If this is not what you are looking for, then maybe a better explanation of exactly what you are trying to accomplish would help.
