Subject Re: wsdl2java NullPointer

OK.  Figured this out and have a fix for it that I'm testing now.    One 
workaround WAS to change the Payload to a top level complexType instead of an 
anonymous type, but that exposed another problem:  if the "Service" name 
is "Service",  the generated code doesn't compile.    I'm fixing that as 
well.
