I am writing a client to a VMWare management web service. In working
with the API, I made a mistake and a SOAP fault was thrown. That is not
the problem. Instead of an WSDL generated exception class being thrown,
I got what appears to be a validation error during parsing of the SOAP
fault. I found someone who had a similar issue, but am not sure whether
the problem is my code, the VMWare web service, or CXF. It would seem
to me that if a web service operation would automatically utilize the
schemas associated with the Service created from the WSDL. The previous
mailing list poster said he solved the problem by using the Java.Net
RI. However, the CXF web site listing the dependencies say the saaj
being used is the Sun 1.3 RI. I am using Maven2 to pull in all the
necessary libraries as well as building the client code from the WSDL.
If anyone can shed some light on what the problem might be, I would be
very grateful.
I did write some code to try and verify the schema associated with the
web service:
List<ServiceInfo> serviceInfos =
client.getEndpoint().getService().getServiceInfos();
for (ServiceInfo serviceInfo : serviceInfos) {
Schema schema = EndpointReferenceUtils.getSchema( serviceInfo );
LOG.info( "Schema = " + serviceInfo.getName().toString() +
"\n" + schema.toString() );
}
Its output was:
INFO: Creating Service {urn:vim2Service}VimService from WSDL:
http://127.0.0.1:8080/sdk/vimService?wsdl
2008-01-23 16:56:08,780 INFO main SampleClient.afterPropertiesSet:158]
Schema = [EMAIL PROTECTED]
The vimService.wsdl imports another WSDL, vim.wsdl, which contains most
of the schema information. I was trying to verify that the imported
schema was being properly associated with the service. You can see from
above that the service/namespace is "urn:vim2Service". However, only
one service/namespace is listed. The imported WSDL's schema's
namespace, "urn:vim2", is not shown and I do not know whether this is a
problem.
The previous posting can be found at the following URL:

Below is the SOAP fault message that caused the exception and below that
is the stack trace. Some relevant fragments from the imported WSDL are:
<element name="InvalidRequestFault" type="vim2:InvalidRequest"/>
<message name="InvalidRequestFaultMsg">
<part name="fault" element="vim2:InvalidRequestFault" />
</message>
The target namespace for these schema elements were
xmlns:vim2="urn:vim2". SOAP fault message:
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/";
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<soapenv:Body>
<soapenv:Fault>
<faultcode>ServerFaultCode</faultcode>
<faultstring>specSet</faultstring>
<detail>
<InvalidRequestFault xmlns="urn:vim2"
xsi:type="InvalidRequest"/>
</detail>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
I believe that this line is causing the problem, but should the contents
of the <detail> element even be validated?
<InvalidRequestFault xmlns="urn:vim2" xsi:type="InvalidRequest"/>
Here is the stack trace:
