I have played with the JSR-299 Reference Implementation "Weld" with the purpose of using it in a stand-alone application, and I have had a look at the documentation, and marveled at the magic.

My question is how the producer of a given object to be @Inject'ed is found?

Either the java compiler produces hints for annotations which is easily found by the classloader, or the complete classpath must be traversed loading all classes to see what they do which sounds highly inefficient to me, or it is a completely different approach.

What is the trick?

I'm starting a new project now. I have to choose technologies. I need something light, so no EJB or Seam. On the other hand I need JPA(Hibernate or alternative) and JSF with IceFaces.
