Description

I'm building my DTOs using wsdl2java and tried to set up a JaxWsProxyClient or -Server which results in

org.apache.ws.commons.schema.XmlSchemaException: Schema name conflict in collection

The offending DTO is an Exception object:

@WebFault(name = "parameters", targetNamespace = "http://www.w3.org/2001/XMLSchema")
public class SimpleFault extends Exception {
private java.lang.String parameters;
....

Sources from WSDL:

...
<wsdl:message name="SimpleFault">
<wsdl:part name="parameters" type="xsd:string"></wsdl:part>
</wsdl:message>
...
<wsdl:fault name="Servicefault" message="tns:SimpleFault" />

The offending Namespace http://www.w3.org/2001/XMLSchema is already added on schema collection instantiation and thus a conflict is determined as soon as the SimpleFault is hit on initialization.

I have devleoped a standalone test case you only need to extract and run "mvn test" for reproducing this. How can I upload it?
