<div class="block">The <code>Resource</code> annotation marks a resource that is needed
by the application. This annotation may be applied to an
application component class, or to fields or methods of the
component class. When the annotation is applied to a
field or method, the container will inject an instance
of the requested resource into the application component
when the component is initialized. If the annotation is
applied to the component class, the annotation declares a
resource that the application will look up at runtime.
<p>
Even though this annotation is not marked <code>Inherited</code>, deployment
tools are required to examine all superclasses of any component
class to discover all uses of this annotation in all superclasses.
All such annotation instances specify resources that are needed
by the application component. Note that this annotation may
appear on private fields and methods of superclasses; the container
is required to perform injection in these cases as well.</p></div>
