> I'm trying to use the cxf extension that allows to map exceptions to reponses. The issue I have is that exceptions raised in setXX methods annontated with @PathParam for example are caught and produce an internal server error. This prevents from performing usefull parameter validation from the setter methods, where they could benefit to all services.
> Attached in a sample application that defines a custom mapper, and raises exceptions either in a setter or a service method.
> Once deployed, I do get for:
> http://localhost/testexceptions/a/b/fail_in_inject
> where the exception is raised at the setter level an HTTP 500 response, with entity
> <ns1:XMLFault 
>     xmlns:ns1="http://cxf.apache.org/bindings/xformat">
>     <ns1:faultstring 
>         xmlns:ns1="http://cxf.apache.org/bindings/xformat">javax.ws.rs.WebApplicationException
>     </ns1:faultstring>
> </ns1:XMLFault>
> and a stack in the server logs, when
> http://localhost/testexceptions/a/b/fail_in_serve
> where the exception is raised at service level correctly returns HTTP 400
> One sould be able to use the setter methods (or the resource constructor) to perform parameters validation, and property return errors.
> Tested with tomee 1.6.0, which ships with cxf-2.6.7
