> I am trying to generate Java code using CXF to work with a third-party tool which they
provide as a web service.  I have attached the WSDL for their service to this message.  When
I try to run the wsdl2java tool on it (using either CXF 2.0.5, which we've used before, and
currently use for one other project, or with 2.2.3, which I downloaded when I started having
problems), I get a NullPointerException with no useful error message:

> So it seems like there is an issue with conforming to the WS-I Basic Profile.  However,
I was under the impression that conforming to the BP was optional, and that a WSDL can still
be valid even if it does not conform.  I am sort of assuming that CXF is providing this message
as informational, rather than as a requirement, but I don't know.  Is it possible that this
violation is what's causing the NullPointerException?  And since this WSDL seems to be valid
WSDL, even if it doesn't conform to the Basic Profile (it passes the validation at http://www.validwsdl.com/,
for example), is there a way to get CXF not to require that it conform, and still generate
Java client code?  Since this is a third-party tool, we don't have the option of changing
the WSDL or the service, so I'm hoping I can find a way to make this work.

> I will attach a copy of the WSDL file we're using.
