RE: JAXRS outFaultInterceptors

[Vitaly Peressada]

I did see ExceptionMapper but even after implementing it I would not solve my 
design problem. I want to find a single central place in CXF JAXRS stack where 
I can:

try {
      // invoke service
}
catch (MyAppException me) {
        ServerError se = new ServerError();
        se.setErrorCode(me.getError().ordinal());
        se.setErrorMessage(me.getError().name());
        return Response.error().entity(se).build();
}
catch (RuntimeException re) {
        ServerError se = new ServerError();
        se.setErrorCode(StatusCode.INTERNAL_SERVER_ERROR);
        se.setErrorMessage(StatusCode.INTERNAL_SERVER_ERROR.name());
        return Response.error().entity(se).build();
}

By the way, I also tried 
http://cwiki.apache.org/CXF20DOC/jax-rs.html#JAX-RS-Custominvokers but was not 
able to hit breakpoint on exception.

Any other ideas? If not, I guess I had to resort to Spring AOP method 
interceptors...

Hi

I will investigate.

In meantime, you might want to implement a JAXRS
ExceptionMapper<YourException> instead and register it as a provider.

At the moment one can't register CXF interceptors as JAXRS providers,
one needs to use inInterceptors/outInterceptors instead.

Thanks, Sergey

I am trying to setup a custom exception handler which would catch
exception from service methods and translate them in Response.error and
custom xml.

Try 1
Use <jaxrs: outFaultInterceptors>
Spring complained

Try2
<jaxrs:server id="infraRedAuthenticationServiceJaxrs" address="/user">
                                <jaxrs:providers>
                                                <ref
bean="authInterceptor"/>
                                                <ref
bean="exceptionInterceptor"/>
                                </jaxrs:providers>
                                <jaxrs:serviceBeans>
                                                <ref
bean="userService"/>
                                </jaxrs:serviceBeans>
                </jaxrs:server>

Where exceptionInterceptor is
public class ExceptionInterceptor extends
AbstractPhaseInterceptor<Message> {

      public ExceptionInterceptor() {
            this(Phase.MARSHAL);
      }

      public ExceptionInterceptor(String phase) {
            super(phase);
      }

      @Override
      public void handleMessage(Message message) throws Fault {
            message.toString();

      }

      @Override
      public void handleFault(Message message) {
            super.handleFault(message);
      }

}

but my break points are not hit when throwing exception from service
method
      @GET
      @Path("/generalexception")
      public Response throwUserException() throws Exception {
            throw new Exception("Foo");
      }
