QTE
Most enterprise software projects have a large portion of junior or 
mid-level developers so [interesting multi-threaded solutions] is not 
really a practical way of scaling the Java architecture for enterprise 
systems.
UNQTE

This should be written on huge billboards.

BEA Tuxedo (a pre-Java "application server" sort of thing) uses 
multi-process model similar to FastCGI, and I've never heard of any 
scalability problems with it, other than deadlocks or full table scans 
at the DB level. If there is not much DB contention, the application 
logic itself scales to tens of CPUs easily.

BEA Weblogic, on the other hand... is quite different :) I have yet to 
see a J2EE app that would scale to more than 5 CPUs without some fancy 
clustering. At least, no such thing has ever existed in our office.
