Unexpected element type: QName vs. string

Question

Hello,
i tried to run the "web service" example code of the book "Core Java" (2004). The program is a window where you can search for book authors in Amazon. But executing the client program results in:
Exception: java.rmi.RemoteException: Runtime exception; nested exception is:
     unexpected element type: expected={http://www.w3.org/2001/XMLSchema}QName, actual={http://www.w3.org/2001/XMLSchema}stringYou can find the code below.
Greetings
Alfred

Amazon discontinued the old service. You can no longer get a working developer token for it. When you give it an invalid token, then an error message is produced.
Due to an error in the way Amazon produces the error message (see http://archives.java.sun.com/cgi-bin/wa?A2=ind0303&L=jaxrpc-interest&O=D&P=1513), you don't actually get to see it.
