Well, that's a though one. We are on the servlet-interest list,
after all.
As compared to most other server side web technologies, I think
that Servlets come out on top. Much better than CGI. Cleaner than
ASP. I would say since you're contrasting Servlets with RMI the larger
difference is in the model.
RMI, while remote and therefore more apt to exceptions, is still
basically your standard programming model. Person starts program, person
interacts with program, person closes program.
Servlets, being web based, are a transactional programming model.
Programs written in this way work better when a large amount of
interaction can be done on the client. Then all of the interaction with
the server is done at once. (Yes, we have sessions, so you can connect
these events into a larger program, but I think that the argument still
holds.) If programming was like eating, RMI would be a dinner, servlets
would be in bar (concentrated) form. :) If you need a rich interaction,
more than a standard browser interface can give you, then RMI (and
possibly applets) are more your answer.
