Perhaps. I definately agree on the performance aspect. My personal concern
is a stability one. Basically I just dont believe the servlet model can
offer the same sort of stability that the one-hit page model can,
principally because on a php page, if the code raises an exception, it'll
flatten the page, not the server. There can also be issues with locking ,
'leakyness' (not *really* as big a problem with python, but I've seen it
in java servlets despite the touted magic of garbage collection).
Finally I do believe webware is not too hard to kill. I'm sadly having to
reboot the webware install I maintain pretty regularly.
Now all that aside , heres why I persevere: Webware is good! The webkit
offers a pretty straight forward way to generate persistant servlet stylee
without horrible.java.abstact.compsci.evil brain hurt. Its pythonic and
pythonic is nice.
Any process control stuff is going to need a persistant process anyway.
Maintaining serial connections, listening for state data from devices etc
etc. One aproach has been a little more abstraction.
I put together a system for controling a large security camera network
that works *imaculately* that had this;-
control data<---[pc]->control server<-[xml-rpc]---->interface
|
camera data <---[pc's]->storage<------[mjpeg streams]---+
the beauty of that, is that I had a php interface that could talk to the
server while isolating the control server from 'idiot userfinger land'.
I also put together a little delphi app that had dials and knobs and other
eyecandy, and generally it was a functional well apreciated interface and
worked well. The control server runs webware, but not for the web
interface, but rather for xml-rpc. Strange hack granted, but the structure
of webware suited the task perfectly.
Also handy: It needed no db :) I still cant wrap my head around making
mysql threadsafe.
