Not acceptable.  This problem arises from the same code in JavaBeanHelper 
writer which James "fixed" and then I "unfixed" to fix exactly this problem 
and then was refixed.  Take a look at the generated datatypes/ArrayOfInt and 
ArrayOfOrder classes to see the problem - there's no XmlType set on the 
element fields for the elements inside the array type, and so we end up with 
an NPE.  Don't yet know the right solution for this, but if I manually put the 
setXmlType() statements in, the WSDL gets generated correctly.  We need to get 
this right for all kinds of arrays, and have tests for it, including testing 
WSDL generation.
