late response to servlet api question ? thread

[ed...@gmail.com]

Hi, sorry about the late response to this, but the tomcat list is
refusing emails from my regular address because I am sending from a
dynamic IP address (I am using sendmail on a local machine to send
mail, rather than my ISPs smtp server, heh).

Don't quite understand what your question is -- I'll give it a go.
servlet api is a de facto standard put out by SUN,
the original specs, with which a container such as tomcat, webspere
(IBM), or weblogic (BEA), comply.

Netscape Server (iplanet), IIS or Apache are web servers, that is they
do not *do* servlets and JSPs.
+Apache can be made to serve them up using loadable modules.
Web servers are different beasts to Servlet containers.
Why companies buy a custom, tailored or otherwise proprietary product
is usually because of
+*out_of_the_box* (turn-key) solutions, available(payed for) support.
With an open source product there is quite a bit of learning, tuning,
configuration etc. that you need to
+do.
This can be challenging to company employees who are *used to* lock-in
solutions, and absolutely
+terrifying to unsavvy management, the idea of *no* support and open
(not completely controlled) code,
+can be very challenging.

Personally, I think the *Sun* solution is great.

hth,
kind regards,
Luke
