Non WSDL Based Restful Web Services Cannot Be Registered In OAG 11.1.2.3 (Doc ID 2783286.1)

Last updated on NOVEMBER 30, 2021

Applies to:

Oracle API Gateway - Version 11.1.2.3.0 to 11.1.2.4.0 [Release 11gR1]
Information in this document applies to any platform.

Symptoms

On : 11.12.3.0 version, OEG Policy Studio

There is no Service Manager tab in OAG Gateway 11.1.2.3.0 where REST Services can be registered. Is there any other way to register a REST service?
In policy studio when "https://<HOSTNAME>/api/xml/fills" in Static Router was configured, the WSDL for the customized service handler is unable to be opened.

Steps performed:

Registering SOA web service which will send request to the REST Service.
Deleting the service handler, replacing it with Set Web Service Context (Specifying WSDL of the SOA Service).
Static Routing. (Mentioning the HOST PORT of the REST Service)
Connections Filter
Deploy. The deployment is successful but not able to open the WSDL generated for the relative path mentioned.

Is it possible to register REST Service by any other way with Policy Studio?
