Hi, Since addEmployee is not having a response hence the HTTP 500 response with a fault message. Streaming works only for data services which has a result in return.
By following [1] I was able to reproduce HTTP 200 response with a soap
fault for employeesByNumber operation.
Due to the default streaming behaviour of data services requests, which has
a result
will respond with HTTP 200 and a fault message.
When creating a data service/using existing sample data service, the
streaming has been turned ON by default.
Due to this HTTP 200 + soap response, ESB 4.8.0 is unable to hit the fault
sequence in an in sequence of a proxy configuration.
Using FORCE_ERROR_ON_SOAP_FAULT property was ineffective even after the fix
applied [4].
As a workaround we can configure setup to hit the fault sequence with HTTP
500 response + fault message.
As per [1] to get an HTTP 500 response you have to disable this streaming
behaviour in both service level and operation level.
Here is how to do it.
First go to Home > Manage > Services > List
Select the data service to edit.
Now we have to disable streaming at service+operations level.
Edit Data Service (XML Edit)
i. Include disableStreaming="true" property to the data element [2],
which will disable streaming at service level.
ii. Include disableStreaming="true" property to the operation being
used/other operations planning to use [2],
which will disable streaming at operation level.
iii. Save/Update the configuration.
This disableStreaming="true" property is defined to retain backward
compatibility
since from the beginning default streaming was always enabled and this
property was introduced later [3].
We can perform the above said configuration from UI.
I have tested this scenario by AS 5.1.0 DSS samples and ESB 4.8.0 +
patch0315 and
was able to recreate the scenario and successfully test the workaround
solution.
