There are numerous ways to configure the web server, jserv and oracle database, just so I dont go insane, Im putting them all on the same box, an NT machine. The configuration parts should apply across platforms but the install is different, check the install instructions for each platform.

At the time of writing Apache on NT is not considered to be stable/secure enough for production use, the intent here is not to configure a production server but a sand box for experimentation. See the apache documentation about the release of Apache on NT.
This DOES NOT mean that Apache will crash every 2 minutes, in fact I've never seen that happen in well over a year - the apache authors realize that the NT version is just not (yet) up to the high standards of apache variants on Unix.

There are other servlet engines you could use, with various web servers, but I'm not going there. I'm not going to open the can of worms that is the install of an Oracle database (others have done this) I am assuming that this has been done.

The configuration I used is as follows

Pentium III 600 MHz , 128 MB RAM (IBM Think Pad)
Oracle 8.05 installed on drive D:/orant instance name ORCL
Apache 1.3.12
Jserv 1.1
JSDK 2.0
JDK 1.1.8.003
Prism 1.0.0

We will go through the install of each component, addressing downloads, installation and configuration for each.

Why are there so many components?

Well Apache is the web server, Jserv is the servlet engine, the jsdk and jdk cannot under Suns java license be released with jserv, so we need to install them to allow the servlet engine to work JDK - Java Developers Kit JSDK - Java Servlet Developers Kit.
And last but not least Prism, which is the servlet that allows html/xml to be generated from the database using pl/sql (ie the pl/sql cartridge replacement).
