Go back to using Java2WSDL again

Go back to using Java2WSDL again

This reverts the changes to use SimpleAxisServer in favor of (again)
using the Java2WSDL program locally. The main reason for using the more
complex SimpleAxisServer "approach" was that before classes in the util
package was moved to the motedata package it ended up in the namespace:
"http://util". This is no longer a problem and the differences in the
generated WSDL documents are minimal:
