I'm the author of the 3 part blog series that you've referred to. I've
obviously tried it and it works but I'd encourage others to give it a
go. There was a bit of jumping through hoops to get it working but
hopefully it was just me that needed to do the hoop jumping and others
will be able to follow what I've described without too much trouble.

It started out as an idea to use the Force.com Web Service Connector
GAE API to perform the marshalling and unmarshalling in order to
expose a SOAP web service. I guess I achieved that but it also uses
quite a bit of the Spring Web Services API to achieve the end result.

I agree that the custom marshaller and unmarshaller implementations
were a bit complex.  As I mentioned a few times during the three
posts, I have a feeling that there may be parts of Spring Web Services
that can be used almost out of the box (or with minimal extension) to
perform the marshalling and unmarshalling of the XML. This would make
the Force.com WSC marshaller/unmarshaller unnecessary. Obviously JAXB
doesn't work on the Google App Engine yet but perhaps Castor or XML
Beans? I was going to give this a go for my next blog post but
unfortunately work has been very busy recently and I've been taking
work home to do during my spare time, but when things free up a bit
I'm planning to give the other marshallers in Spring Web Services a
go. So keep an eye out in a month or so.

It may be that Google white list JAXB at some point and then using
Spring Web Services would be simpler. Having said this, Spring Web
Services in general is fairly complex to get your head around. JAX-WS
is far simpler to use but I doubt we'll ever see that on the Google
App Engine. It is simple on the surface but fairly complex under the
hood I think.
