Thanks for the quick reply, Steve.

There seems to be a common misconception that CDI only works for traditional container-managed components (EJBs, servlets, etc.). But I'm pretty sure that's not the case.
Here's a definition of managed beans from the JEE 6 Tutorial:
http://java.sun.com/javaee/6/docs/tutorial/doc/gjfzi.html
Here's an example of one POJO being injected into another POJO:

Here's another discussion:
http://www.theserverside.com/news/1373391/Dependency-Injection-in-Java-EE-6-Part-1
"Managed beans are a key concept introduced in Java EE 6 to solve some of the limitations we talked about in the previous section with Java EE 5 style resource injection. A managed bean is just a bare Java object in a Java EE environment. Other than Java object semantics, it has a well-defined create/destroy life-cycle that you can get callbacks for via the @PostConstruct and @PreDestroy annotations. Managed beans can be explicitly denoted via the @ManagedBean annotation, but this is not always needed, especially with CDI. From a CDI perspective, this means that almost any Java object can be treated as managed beans and so can be full participants in dependency injection."

My sample EAR was greatly simplified and probably a bit contrived. I'm not sure that I will keep the SiteDaoImpl as a POJO in my real app. I may make it a singleton EJB instead. But from everything I've read, CDI should work between POJOs, as I have it setup. The fact that it doesn't seems to imply another bug in GlassFish, which I'd be happy to submit a defect for if someone can confirm this.
Thanks,
