Exceptions

Exceptions will be presented by the Nummervoorziening Service as Soap faults. To distinguish the cause Exception of an operation at the client, the element faultactor will hold the specific Exception. In the detail node, a message node is added with additional information regarding the Exception.

Example of a Soap fault as a response from the Nummervoorziening Service (omitting the Soap Headers): 

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body> 
      <soap:Fault> 
         <faultcode>soap:SERVER</faultcode> 
         <faultstring>RetrieveEckIdBatch has thrown an exception while building the response</faultstring> 
         <faultactor>InvalidBatchIdentifierException</faultactor> 
         <detail> 
            <message>Batch with specified identifier does not exist</message> 
         </detail> 
      </soap:Fault> 
   </soap:Body> 
</soap:Envelope>


The reference clients will contain code in Java and C# to handle these faults and distinguish root causes.
