• If the originating exception is a Business exception and conversions fails should we have a Tuscany standard runtime exception that will have basic message from the originating exception set ? Should we just pick one of the business exceptions on receiving operation ? This might be more robust than throwing a runtime exception.
• What runtime exception should undeclared, checked exceptions be wrappered in? Tuscany defined ? just RuntimeException ? java.lang.reflect.UndeclaredThrowableException? I can see an SCA client still wanting to be "robust" capturing this and acting on it.
• Will not directly validate webservices exceptions until axis binding is at incubator-snapshot (kernel trunk) level
• How are we currently mapping operations during wiring in Tuscany with respect to exceptions ? Need to see if Exceptions are part of operations signature.

Implementation Decisions

• Currently we are unwrappering at the TargetInvokerExtension all exceptions and passing them on the message path.
• System exceptions happening during the processing of a message are thrown up the stack.
• We have made some decision on the support of SDO exception wrappers and example of can be seen in the exceptionXbindingTest iTest
  This closely resembles the JAX-B pattern in dealing with faults. One exception is we currently have a FAULT_ELEMENT field type QName on the exception to help tie back to original wsdl element it is associate to.
