What I mentioned only with one sentence in my blog was the addition of
the AnnotationInjectable:
"jersey now provides an AnnotationInjectable, that can be provided for
some annotation, so that the injectable is asked for an instance of a
class if a field of some resource is annotated with the specified
annotation"
So you could override ServletContainer and especially
initiate(ResourceConfig rc, WebApplication wa)
therein and add your EJBAnnotationInjectable for your @EJB annotation to
the WebApplication. EJBAnnotationInjectable can then override
public Object getInjectableValue( Object o, Field f, EJB a )
and provide the desired EJB.
Right now you need jersey from the spring integration branch for this
[1], but Paul plans to merge this into the trunk these days.
Cheers,
Martin
