-----------------------------------------------------------

Since current CXF 's WrapperClass{In|Out}Interceptor just support the JAXB databinding, and there a quit difference between JAXB and XMLBeans type Instantiation, so you got that kind of error.

To walk around this issue just has DanKulp said , I tried the method 1), if the SEI's method parameter is void, I still get the Wrapped method like this.
 
 {code:java}
@ResponseWrapper(localName = "pingMeResponse", targetNamespace = "http://apache.org/hello_world_soap_http/types", className = "org.apache.helloWorldSoapHttp.types.PingMeResponseDocument")
    @RequestWrapper(localName = "pingMe", targetNamespace = "http://apache.org/hello_world_soap_http/types", className = "org.apache.helloWorldSoapHttp.types.PingMeDocument")
    @WebMethod
    public void pingMe() throws PingMeFault;
 {code}

So we need to find other way to resolve this issue.

> I have modified the wsdl_first sample to use the xmlbeans databinding.  Xmlbeans is generating both an interface and a concrete type for each of the types defined in my wsdl. This is causing a problem with CXF as its using the interface rather than the impl to instantiate request and response wrapper classes. 
> This results in the stack below which shows the InstantiationException.  Note the type is org.apache.helloWorldSoapHttp.types.SayHiDocument - I think it should be .. org.apache.helloWorldSoapHttp.types.impl.SayHiDocumentImpl ?
