Hi
I updated the exception handling section with few extra details, I added a link to a simple exception mapper used by Spring Security
tests and also linked to a custom CXF out fault interceptor.
So in summary here're the options for catching all the exceptions :
- register a mapper like ExceptionMapper<Throwable>
- register a custom out Fault Interceptor
- register a custom Servlet filter (provided that the propogation is not turned
off)
Finally, if you'd like no exception traces reported with HTTP responses then
just disable the propogation.
Also, I wonder
if you can tell why spring AOP is not working on the CXF impls? Tried to
debug it, but have no clear picture yet. It seems like injection hicks up
on the wsContext member of the base class of my Impl class.

This exception trace looks similar. If you have a JAXWS WebServiceContext field then use a setter instead. Similarly for JAXRS
MessageContext
hope it helps, Sergey
Hi Mustafa!
Yes, I need to be able to have a centrally controller backstop for all
exceptions coming out of my mackages, mostly .*Impl classes and custom
interceptors such as i.e. Auth interceptor. Soap already kind of does it for
me by wrapping it into a generic Fault (I actually wanted MyException class
instead, but I can live with Fault for unexpected errors on the Soap side.
The jaxrs REST side behaves differently by exposing full stack traces, which
is what I don't want clients to see - there is log file for that purpose..
The mapper sounds like what I could use, do you have an example how to
intercept or map a Exception and rethrow MyException instead? Also, I wonder
if you can tell why spring AOP is not working on the CXF impls? Tried to
debug it, but have no clear picture yet. It seems like injection hicks up
on the wsContext member of the base class of my Impl class.

From my understanding you basically want a centralised place to handle
exceptions and a way to control what is returned to the client? We use an
exception mapper which receives all possible exceptions and you can then
return the desired response object based on the exception. We have a many
to one mapping between exceptions and the status codes we return in XML
format and are able to handle all exceptions ensuring that not undesired
responses get sent back to the client.
Have a look at

Subject: CXF jaxrs REST exception stack trace propagated to REST client,
can exception be wrapped up or filtered out or AOP intercepted?
Hi All,
Is there a way to Not propagate unchecked exception stack traces back to
the
client?
Use case: I have a port, that expects certain parameters, if one of them
is
null
it may throw unchecked IllegalArgumentException, which could be rectified
if
it was
all under my control.
Imagine that other team members adding new ports and not wrapping it up
completely.
What I wanted was to have a way to control what goes out to the client
hopefully in one place.
For instance I have defined WSBaseException from which all other WS layer
exceptions
should be derived and thrown out of the WS layer (annotated with
WebFault).
First thing I did, I tried try AOP "after-throwing" pointcut, which is
where
I was hoping to intercept all outgoing exceptions and wrap them up in the
WSBaseException for anything
that would come out unless it was already WSBaseException, but that didn't
work, still debugging why it fails, btw AOP config and exception is
below:
But my question is mostly about how to do this without
extra AOP, does CXF has a way of dealing with this situation already, may
be
I'm missing something?
Thanks,
-Vitaly
