That tutorial leaves a lot for you to figure out.  Basically, you need
to set up an appropriate environment so that the Ant tasks work properly
and all the right values are included in the build.properties files and
the targets.xml files in all the right spots.  When you execute the
default Ant task (named build), it refers to the WSDL file for the
"MyHelloService" and uses wscompile (I think) to create Java code from
it.

If the directory structure is still as I remember it, you can look in
the jaxrpc/commons directory for the targets.xml file there, and find a
target named "generate-stubs".  In its <param> entry's "value"
attribute, add "-keep" before the "-d" (it'll work elsewhere, that's
just where I put mine).  That will cause the Java code created to remain
in your "build" directory after it's done.  You can look through this
code and compare it against what you see in the WSDL file to get a feel
for how this all works.
