jsp - How to set cookie in Jersey?

Question

I am using jersey jax-rs in myeclipse as backend of my project and jsp as frontend. I want to set cookie from server after successful login. In the jersey's official document, I can only find how to get cookie by jersey. Does anyone can give me a demo to do such things?

This is my login part and I return a response and redirect to URL "/" which means index.jsp.

@Path("/login")
@POST
@Consumes("application/x-www-form-urlencoded")
public Response login(@FormParam("email") String email,
        @FormParam("password") String password) {
    Map<String, Object> model = MapFactory.newHashMapInstance();
    model.put("email", email);
    model.put("password", password);
    loginCheck(model);
    if (model.get("emailCheck").equals("ok")
            && model.get("passwordCheck").equals("ok")) {
        return Response.ok(
                new Viewable("/index", new NewCookie("name",
                        "Hello, world!"))).build();
    } else {
        return Response.ok(new Viewable("/login", model)).build();
    }
}

This is my "/" part:

@GET
@Produces("text/html")
public Response getIndex(@CookieParam("name") String name) {
    HashMap<String, Object> model = MapFactory.newHashMapInstance();
    model.put("name", name);
    System.out.println("cookie name:" + name);
    return Response.ok(new Viewable("/index", model)).build();
}

Every time I run this code, I find that I cannot get cookie from the index part. If you also ever bothered by this question and finally solved it, plz give me some directions, thanks.

To set the cookie in your example, you can do something like this:

return Response.ok(new Viewable("/index", model))
               .cookie(new NewCookie("name", "Hello, world!"))
               .build();

But if you want to redirect to "/" you would also need to return 3xx response instead of 200, for example:

return Response.seeOther("/")
               .cookie(new NewCookie("name", "Hello, world!"))
               .build();
