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
