I personally have nothing against the use of Java,
but I try to be balanced in my view of it and consider
it just one tool among others. This means it is not
necessarily the right tool for every job.
I've worked with engineers who haven't seen my app,
read the MRD or PRD, yet tell me, "We'll build this
in Java!" It may be the correct choice, then again
it may not be.
There are many issues to be considered with the choice
of language from performance/scalability, maintainability,
cost of ownership, security, pool of available engineers,
There are also implementations of Java on
both the client and the server side to consider.
On the client side, where there is a need for
lightweight apps (like mobile phones or small applet
for desktop), Java can be wonderful.We've used it for
some viral marketing software with success.
Although even in this case, we found the Sun proclamation
"write once, run everywhere" to be completely false.
I was actually tempted to file a claim with the FTC
against Sun (McNealy) for false advertising.
On the other hand, when we attempted to develop a
cross-platform streaming media player (targeting Mac
and Windows desktop)in Java with JMF to build a cross-platform
media player -- Java wouldn't work, since it only supported
MPEG-1 which was a show stopper.
On the server side, though, there are lot's of
other languages that for certain instances may
work better as Java still has some short comings
in being semi-compiled and interpreted.
There is perl (do I hear the groans?) in which apps
can be quickly built and if built correctly can be
both secure and scalable. If there are extra concerns
of scalability, then mod_perl can be quite effective.
There is always C as well, python, too.
I've personally been involved in several enterprise
applications (an online billing mediation service, content
mgmt system and online electronic publishing system) that were
written/attempted to be written in Java and took forever to
write -- with cost overruns and the apps were late to market
or never made it.
In one case, a person I know re-wrote the entire
billing mediation service in mod_perl in 3 months and
basically saved the company.
The issue for these companies may have been
poor product design, weak engineering talent,
incompetent management but also the incorrect
choice of programming language may also have been
