Error parsing response envelope on Linux, but not windows 2000.

["Sanders, Corey" <Co...@stercomm.com>]

I am experiencing wierd behavior using the SOAP-2_2 API. Using the code
fragment attached below, I can make a successful call from my SOAP client on
a Windows 2000 machine into an Apache SOAP 2.1 service running on JRun. But,
using the _exact_ same code, against the same service, but from my Redhat
7.2 machine, I am getting the attached exception. I have verified that the
classpaths and jars are the same on both machines. The client JVM is the
same - JDK1.3.1_01. Both clients are running under Weblogic 6.1.

Stepping through the SOAP source in my debugger, I can see why the error is
occuring. While processing the response envelope (attached below), the API
is unable to locate a namespaceURI for the "xsd" namespace. But the xsd
namespace is defined  in the Envelope tag! Besides that, I cannot see why
the behavior would be different between the two platforms. And I am pretty
confident there is a platform issue because I have been able to duplicate
the problem on two different Linux machines and unable to duplicate the
problem on two different Windows 2000 machines.
