I was looking into an issue a coworker ran into calling the Xmethods =
Babelfish translation service (specifically to test out non-ascii =
chars), and decided to try a simple WSDL2Java based client against the =
service to see how it compared to how he was using AXIS (1.2RC2), and I =
was able to reproduce nearly the same problem.
=20
I figured I'd ask here before digging too deep on this one - hoping that =
maybe someone can spot either what I'm doing wrong or what the service =
itself is doing wrong, or what may be a bug in 1.2RC2?  I'm sure I've =
seen non-ascii chars work just fine in AXIS response envelopes before, =
so I'm not sure what's up with this one...
=20
WSDL:  http://www.xmethods.net/sd/2001/BabelFishService.wsdl

Service is at:  http://services.xmethods.net:80/perl/soaplite.cgi

Sample request envelope

With an HTTP content type header of:
Content-Type: text/xml; charset=3Dutf-8

The AXIS Fault I'm getting back in the simple WSDL2Java generated client =
(unit test hand-modified to just run as a standalone client without =
Junit) is slightly different than what my coworker is getting, but both =
are the same below Message.getSOAPEnvelope in the stack, where it's =
trying to parse the XML for the SOAP envelope in both cases, via the =
DeserializationContext for the response envelope.
=20
The encoding for the response envelope is marked UTF-8 as is the HTTP =
response headers associated with that envelope.  The envelope looks =
fairly valid by eye and a simple Java program that just posted the above =
request to the same service and read and dumped out the response using a =
UTF-8 encoding didn't complain about any of the bytes in the response.

Note:  I don't get the error if the response contains just ascii chars.
=20
Here's one exception I'm getting in the standalone test (MustUnderstand =
checker asks for the SOAP env):
=20
	{http://xml.apache.org/axis/}stackTrace:org.xml.sax.SAXParseException: =

And here's another another almost identical one from another batch of =
client code using AXIS directly (without WSDL2Java)
