Hm. Well, I tried making it a @Stateful bean, and went through some rigmarole with
needing to put the init() method in the local interface.
But it still fails. I now get this (sorry for the big mangled stacktrace, this forum
isn't kind to long code lines):

You guessed it... same darn NullPointerException because entityManager is null.
What am I missing? I have plain old POJOs in my session scope that I inject an
EntityManager to in exactly the same way. Why is this not working at application scope?
Maybe there's another way to do what I'm wanting to do here... basically, I want
there to be some application component that maintains a list of "synchronizers",
one synchronizer per Site entity that exists in the database. Perhaps I want a stateless
component that extracts the list of sites, and then have the application component inject
that SiteList and construct its synchronizers from that? I'll try that next (but not
tonight, it's 1 AM ;-). But it'd still be nice to know the theory behind why what
I'm doing here isn't supported... or know what I'm doing wrong!
Thanks,
Rob
