Hi,
Sorry for the late response as we were heads down on the 1.0 release.
My understanding is that if a java exception representing the business issue
(for example, CustomerNotFoundException) is thrown, it should be mapple to a
WSDL fault as defined by the WSDL operation. Otherwise, it will be wrapped
to a generic fault and propagate back to the client as a system exception.
In the cases of business exceptions, they are usally generated from the WSDL
by a tool like WSDL2Java or JAX-WS wsimport. The JAX-WS spec defines the
pattern for java exceptions corresponding to the WSDL fault.
Please try our 1.0 release at
http://incubator.apache.org/tuscany/sca-java-releases.html. Your feedback
will be appreciated. Any contributions are welcome!
Thanks,
Raymond

Subject: Java-Exceptions <--> WSDL-Fault Mapping
Hi All,
Is it possible to throw a java-exception in a Tuscany/SCA-Webservice and
catch the exception in the Tuscany/SCA-Webservice-Client.
I tried to extend the HelloWorldws-Example to throw a java exception but
there seems to be something wrong with
the mapping to the wsdl-fault. Is there any information how to create
WS-faults with Tuscany/SCA.
thanks.
Björn
