Hmm, I'm somehow confused. Spring 2.5 users already can use the Spring
annotations and don't have to use our @Inject. Spring does the whole job
based on the spring 2.5 annotations. Though, I don't want to depend on
the spring 2.5 annotations but still support spring 2.0.
You might have a look at AutowiredBySpringSingletonResource and
AnnotatedSingletonResource for the current usage of spring 2.5
annotations.
And I'm aware we need some spring example, perhaps I find the time to
create one this week - if no one else comes first :)

Probably my holiday was too long, again I'm not sure if I understand
you ;)
Trying to express what I understood/read: You want that jersey(-spring)
reads the lifecycle from the spring annotations, if no jersey lifecycle
is declared but a resource class is annotated with @Component?
So the ComponentProvider would tell jersey of what scope a component is,
if the Scope is not defined by some jersey annotation?
