Handling Different Response Selections in the SDL
Handling Different Response Selections in the
SDL
NonStop SOAP supports marshaling different response messages based on selection
criteria specified in the ResponseSelection elements of the SDL. A response can be
marked as default and will be used when no selection criteria is specified or if none of
the conditions specified in the selection criteria are true.
In cases where a default response is not specified and none of the conditions in the
selection criteria are true at run time, the SOAP server encounters an exception and
returns a SOAP fault with this message in the "detailString" element of the fault:
"Application error - internal processing error"
To avoid the above exception, specify a default response as part of the response
selection criteria as shown in this sample SDL fragment.
