Call 1 jersey resource class from another Jersey resource class with @Context ServletContext

I have Jersey resource class A calling a method in resource class B.Both classes have a @Context ServletContext servletContext at the class level. When I instantiate class B to call it from resource class A using its empty constructor, servletContext is null in the class B method being called. Is there any Jersey framework way I can call class B and yet have the servletContext retain its values/attributes from class A.
