Glen Mazza commented on CXF-1136:
---------------------------------

In comparing Metro and CXF outputs, I think I found the problem.  You appear to be using a nonstandard form of creating an exception that does *not* result in the underlying CustomException exception being stored.  I do not know why CXF provides this form.

In your service class, you call:
    throw new CustomException("custom error");

In other words, the first of these three possible constructors:

    public CustomException (String message) {  super(message);  }

    public CustomException (String message, demo.hw.company.CustomExceptionType customException) {
        super(message); this.customException = customException;  }

    public CustomException (String message, demo.hw.company.CustomExceptionType customException, Throwable cause) {
        super(message, cause);  this.customException = customException;  }

But only the latter two causes the customException to be stored.  

Metro's wsimport, at least JAX-WS 2.1 version, does *not* provide for the top constructor that you were unwittingly using, so you must use either of the bottom two.  I don't know enough about why we provide the first constructor variant--either it's a JAX-WS 2.0 construct or a good intention that may not be that helpful after all.  (Team:  should we get rid of the first constructor variant?  Is this even called for in JAX-WS?)

At any rate, if you look at how I constructed EntryAlreadyExistsFault in function addWordEntry() in [1] below, you'll see how you can create your exceptions so that they can be trapped on the client side.

HTH,
Glen

>    Affects Versions: 2.0.2
>         Environment: WIndows XP
> Java SDK 1.5_0_12

> I modified the apache-cxf-2.0.2-incubator\samples\java_first_jaxws web service to throw a custom exception and a custom request and response object like so:
> public interface HelloWorld {
>     Response sayHi(Request text) throws CustomException;
> }
> CustomException is a CustomExceptionBase with two string properties. CustomExceptionBase is a java.lang.Exception
> The CustomException appears in the WSDL but the CustomExceptionBase is missing. When the service is invoked and throws a CustomException the soap response is:
> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
>    <soap:Body>
>       <soap:Fault>
>          <faultcode>soap:Server</faultcode>
>          <faultstring>custom error</faultstring>
>       </soap:Fault>
>    </soap:Body>
> </soap:Envelope>
> I am expecting to see the CustomException serialized in the Envelope/Body/Fault/detail node.
