client.invoke throws error: Type 'xs:string' is not validly derived from
the type definition, 'echo', of element 'ns3:echo'.
This is due to badly formed XML generated by CXF.
The test code is a simple echo and the XML is derived by CXF using the
WSDL.
It works for a simple Java web service, but fails for a .NET one.
The client code is basically:
JaxWsDynamicClientFactory dcf =
JaxWsDynamicClientFactory.newInstance();
// build security header - only for .NET service
Client client = dcf.createClient(-URL to the WSDL-);
Object[] results = client.invoke("echo", "Hellooooo");
The GOOD generated XML for the Java web service looks like:
<SOAP-ENV:Body>
<ns3:echo xmlns:ns2="http://com/netspend/ws/ski/types/";
xmlns:ns3="http://neo3.netspend.com/";>
<arg0>Hellooooo</arg0>
</ns3:echo>
</SOAP-ENV:Body>
The BAD xml for the .NET service is:
<soap:Body>
<ns3:echo xmlns:ns3="http://com/netspend/ws/ski/";
xmlns:ns2="http://com/netspend/ws/ski/types/";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="xs:string">Hellooooo
</ns3:echo>
</soap:Body>
You can see 1) that the end of the operation element (echo) and the
argument element are squished together into one
and 2) the string type element has an inappropriate "xs:" prefix in the
quoted string.
The CORRECT xml for the .NET service (from other clients) is:
<soap:Body>
<ns3:echo xmlns:ns3="http://com/netspend/ws/ski/";
xmlns:ns2="http://com/netspend/ws/ski/types/";>
<ns2:echoText>Hellooooo</ns2:echoText>
</ns3:echo>
</soap:Body>
The bad XML looks like it is using (see .NET WSDL below)
<xs:element name="echoText" type="xs:string" />
but is grabbing the type rather than the name.
The (simplified) WSDL for the Java web service is:
