Hi,
I haven't noticed anyone mention that EJB/J2EE is just one in a long line
of technologies that have been applied to problems that may not require
them. Some applications are built on top of CORBA that could have used
TCP/IP sockets, and some applications are built on a commercial RDBMS
that could have used flat files.
Some of this is caused by vendors that overhype their benefits. Some of
it is caused by developers who only apply what they can learn quickly,
and avoid capabilities that they don't understand (i.e. if I already know
JDBC and servlets, why bother learning EJB and JSP). John's point is also
a good one: today's requirements aren't the only driver; tomorrow's
requirements (both real and potential). Another factor is the tradeoff
between technology and system administration. One of the major reasons
that many companies try to standardize on a platform is that as the
number of different deployed technologies grow, it becomes difficult
(if not impossible) to find sys admins to keep it all up and running.
One last thought has to do with the Fear, Uncertainty, and Doubt factor.
Which company stands to benefit the most from doubts about the return
on investment available from J2EE technology? IBM? BEA? HP? Any of the
open source vendors? Don't think so. What about Microsoft who's preparing
for the first release of .Net? Anyone out there put it past the evil
empire to fund a Gartner study on how well J2EE has fulfilled its promise
over its first 3 years, then permit them to publish it. I'm not suggesting
that this IS the motivation, just suggesting that it could be.
