Learning Apache Axis - II

I have been trying to understand how to develop a document style web service and it has been a frustrating experience to say the least. There is a lot of code required in the client, a number of interfaces to create, a number of utilities to run/re-run all for just sending an XML document instead of a string. I am fully aware of the benefits of this style but I am wondering if too much complexity would drive developers away from this approach to the more simpler RPC approach.
