You can inject ServletConfig, ServletContext, HttpServletRequest and
HttpServletResponse. So, e.g. if you want to get an object stored in
the servlet request by a filter you can write something like:
@Path(...)
public class MyResource {
public MyResource(@Context HttpServletRequest request) {
Object o = request.getAttribute(...)
...
}
...
}
