             Summary: wsdl2java using wrapper style cannot handle multiple levels of xsd:extension elements
                 Key: CXF-8025
                 URL: https://issues.apache.org/jira/browse/CXF-8025
             Project: CXF
          Issue Type: Bug
          Components: Tooling
    Affects Versions: 3.3.1
            Reporter: James Poje


While converting a project from Metro to CXF 3.3.1, I ran into an issue where wsdl2java (using wrapper style) was generating the port type interface without errors but some method parameters were totally missing.

Debugging found that some of our schema types use multiple levels of xsd:extension and CXF seems to stop looking after one level (in org.apache.cxf.tools.wsdlto.frontend.jaxws.processor.internal.ProcessorUtil::getWrappedElement).

Example element similar to our original issue: the port type interface would generate with the "id" parameter and without the "parentId" parameter (more complex example will be in the PR):
{code:java}
<element name="someParameter" type="x1:someParameterType"/>
<complexType name="someParameterType">
    <complexContent>
        <extension base="x1:ParentType">
            <sequence>
                <element name="id" type="xsd:string" minOccurs="1" maxOccurs="1"/>
            </sequence>
        </extension>
    </complexContent>
</complexType>
<complexType name="ParentType">
    <complexContent>
        <extension base="x1:EmptyGrandParentType">
            <sequence>
                <element name="parentId" type="xsd:string" minOccurs="1" maxOccurs="1"/>
            </sequence>
        </extension>
    </complexContent>
</complexType>
<complexType name="EmptyGrandParentType"/>{code}
 

This schema structure appears valid (please correct me if this is wrong) and has been in use with Metro for some time, so I think this just needs a small fix.  I have a proposed patch+test PR to submit shortly.  It simply adds multilevel traversal to the original work supporting xsd:extension elements in [CXF-2193|https://issues.apache.org/jira/browse/CXF-2193].

Please let me know if I can clarify or add any other info.
