Criticisms of EJB

My top 5 pet peeves with the EJB specification - Roland Barcia - Dec. 2004
CMP Boone
EJB vs COM+ - Debate between Ed Roman and Roger Sessions - 1999
EJBs from a critical perspective - TechMetrix - Dec. 1999 - Dated but some good points
Comparing MTS to EJB - Microsoft oldish criticism of EJB 1.0 - July 1998
Sessions' critical look at EJB - Opinionated, but informative, series on EJB vs. MTS. Sessions wrote the original CORBA persistence service - now deprecated. Subsequently he has vociferously embraced the Microsoft COM/MTS line - looks like there are some hard personal feelings against CORBA...
and Rickard Oberg's reply to Session - more
