Hi,
I searched the archives, and couldn't find any info on this. I'm far from an
expert with web services, so I hope this isn't a dumb question, but even if it
is, any help would be appreciated.
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:

There is no indication here as to what the problem is, and searching the web
and the us...@cxf archives, I don't find anything that seems related to this
error.
When I try running with -validate to see if the WSDL is valid, it gives me the
following error:
jrob...@yggdrasil,11:17am,[~/tmp/newcxf/apache-cxf-2.2.3/bin]% ./wsdl2java -d

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.
Thank you in advance for any help or advice you can offer.
