Error subflow for the Service Facade to WebSphere MQ: one-way with acknowledgment pattern

This subflow tests whether an error message must be written, which is determined by the user-defined property: ErrorLoggingOn.

  1. If you have configured the pattern parameters to include error messages and the user-defined property: ErrorLoggingOn is selected, an error message is prepared and written to the error queue.

    Details of the exception are written as an XML message. These details include:

    • Broker name
    • Flow name
    • Time stamp
    • Summary of the exception data

    The summary of the exception data contains the message flow label, error number, text description, and a list of inserts giving further details.

  2. If the message to the provider has been written and a reply sent to the requester, no further action is taken.
  3. If the message to the provider has not been written, an exception is produced that causes a SOAP fault to be returned to the requester.
