Security information is available by obtaining the SecurityContext using @Context, which is essentially the equivalent functionality available on the HttpServletRequest.

SecurityContext can be used in conjunction with sub-resource locators to return different resources if the user principle is included in a certain role. For example, a sub-resource locator could return a different resource if a user is a preferred customer:

@Path("basket")
public ShoppingBasketResource get(@Context SecurityContext sc) {
    if (sc.isUserInRole("PreferredCustomer") {
        return new PreferredCustomerShoppingBaskestResource();
    } else {
        return new ShoppingBasketResource();
    }
}
