The calculator example does work. The source code is cleverly hidden at
/ADC Reference
Library/documentation/WebObjects/Web_Services/Web_services.tar.gz
Try that, see if it doesn't help.

Subject: Calculator Web Service example - log4j/commons-logging discovery
Greetings -
I am new to Apple OS X WebObjects web services, so I will apologize
in advance for the remedial nature of my comments.
Attached to this email please find a compressed pdf form of a stack
trace I consistently got when attempting to invoke the simple
Calculator Web Service. The trace indicates there is some problem
with either log4j or commons-logging. I suspected the WebObjects
installation and ensured I had the latest version of both log4j and
commons-logging. Alas, the problem persisted and I continued to
search until I determined that the problem was mine ... I found a
rogue commons-logging.jar in my own ~/Library/java/extensions folder
that was used when launching the WebObjects server. It was my
impression that the script used to start the WebObjects server would
somehow prefer the /Library/WebObjects/extensions folder over
mine ... but it did not.
I searched through various message threads in this mail list to
determine whether or not anyone else had determined a root cause for
Calculator example failure. I saw lots of questions but no answers
clear enough (in my perhaps audacious view) to help a novice, so I
will register mine here for the record and hope it will save someone
some time going forward.
I also see that folks have had difficulty finding source code for the
calculator and related client. I simply cut and pasted from Apple
documentation for the calculator and built a very simple client. I've
attached them for your convenience here - XCode 2.2 project files.
