What injection mechanism should I use in Java EE 6?

Java EE 6 offers (at least) two dependency injection mechanisms: DI annotations from Java EE 5, such as @EJB, @PersistenceContext, @Resource ... and the new JSR 330. Can I replace the "old" DI annotations with more general JSR 330 annotations?

Are there any advantages or disadvantages of this or that approach? Which one would you use and why?

Go to the JSR 330 annotations. They will work with other DI environments that are being updated, such as Spring 3.0.
