Lalith,
For learning about servlets, I would expect that JDK + JSWDK is probably all you
need. As downloaded, JSWDK can do the things you listed, and it can serve static
pages as well, so you don't need a web server in addition just for that. This is
one major difference between the JSWDK server and the one that was in JSDK 2.1.
The things that JSWDK cannot do for you (versus a more powerful web server or
servlet engine) are things more often required for production applications, not
student projects. Among these things:
* Server-provided security (username/password authentication),
although you can certainly do this yourself in servlet+JSP based
applications.
* Web server access logs (for hit tracking and so on)
* Scalability to large numbers of simultaneous accesses
* Load balancing or other distribution techniques.
* Automatic reloading of servlet classes when you change them
(you have to restart the server).
By the way, on the topic of server-side includes, Luc correctly pointed out that
you can do includes the "JSP way" with no extra software. However, because you
can run any servlets (not just ones you write), you could easily add a servlet
that supports the <servlet> style includes, or "*.shtml" files. There are several
open source packages of servlets like this -- for that matter, writing a
server-side-include servlet yourself should certainly be within your grasp by the
time you finish your studies.
