I used a single *local* SLSB. I would only use EJB now if I wanted to
distribute my business objects--something I normally try to avoid.

So there are not that many situations where I would now use EJB.

There should be no scalable issues compared with using local EJBs. Using
remote EJBs is a different issue but in my experience, as I say in my book,
distributing your business objects is bad for performance and not
particularly good for scalability.

But I'd also like to hear about users' real experiences with Spring... I
don't currently have anything in production on Spring but I've been very
happy with the load testing etc I've done on the code I've developed so far.
