Making sequential calls using Oracle Mediator

Many people are unaware that Oracle mediator can be configured to make sequential calls.
This posting presents an example of a mediator component  that calls a web service,
then combines the web service response data with the original mediator request data
and calls a File adapter with the combined payload.

The composite diagram for this example looks this

Composite.xml

 The processing is completed using a single Mediator component with a single Routing Rule as follows:

Static_Rules

Create this example by following the steps in the full article.

Hi Bob,

Thanks for the example here. Seems this is only possible if the second operation is one-way operation and not a two-way request-response operation.

Hi Debanjan,

yes it seems that the response can only be forwarded to a 1 way service.
As mentioned in the third paragraph at this link in the docs.
http://docs.oracle.com/cd/E15523_01/integration.1111/e10224/med_createrr.htm#BABEJIGC
I have not tried the suggested approach of using a 1 way and request/response in combination mentioned in the same section, but maybe that would be a possible approach.

thanks for pointing out that limitation in the posted example.
