Douglas, Since our <binding.ws> impl uses JAXB by default to map from the XML wireformat to the application Java, the JAXB runtime needs to be able to deserialize into your input/output types. If the types don't contain JAXB annotations, they need to follow the pattern that JAXB expects, i.e. they must contain the no-arg default constructor.
Also I'll mention that we follow the JAX-WS spec in order to map between a Java exception and the platform-neutral fault data it carries. (See "Business Exceptions/Faults" at http://cwiki.apache.org/confluence/display/TUSCANYWIKI/Databinding+Scope for more info. It crossed my mind that maybe your interface is passing java.lang.Exception as an input parameter because you weren't aware of how to "throw" it across <binding.ws> .... or maybe you have a good reason for doing so and it was just a useful example.
