Interceptors
I have two questions about interceptors:
1) What is the difference between when an inFaultInterceptor and an
outFaultInterceptor get called? For example, if I receive a message on a
jaxws:endpoint, a business object does some processing as a result, then
that throws some exception based on business rules (e.g. data integrity
issue, user not authorized, etc. ) how does CXF know which
faultInterceptor to call?
2) Is there a "catch-all" interceptor that acts like a "finally"
block? I want to execute some code after every message completes
processing, regardless of whether a fault occurred or not. Right now it
looks like I need to include my interceptor in the outInterceptor and
outFaultInterceptor chains like this:
<jaxws:endpoint id="myEndpoint" implementor="#endpointService"
address="/soap/endpoint">
<jaxws:features>
<bean class="org.apache.cxf.feature.LoggingFeature"/>
</jaxws:features>
<jaxws:inInterceptors>
<ref bean="myInInterceptor"/>
</jaxws:inInterceptors>
<jaxws:outInterceptors>
<ref bean="myCatchAllInterceptor" />
</jaxws:outInterceptors>
<jaxws:outFaultInterceptors>
<ref bean=" myCatchAllInterceptor" />
</jaxws:outFaultInterceptors>
</jaxws:endpoint>
Thanks,
Morgan

The inFaults are the interceptors on the client side for fault handling
(when
the fault comes "in" from the server). The outFaults are for the
outgoing
faults on the server side.

No. You would need to put it on both the chains. (and on both the
"in"
chains on the client side).
