Odata support in OSB 12c

3210294Jan 20 2017 — edited Jan 23 2017

Hi Everyone,

I was wondering if OData is supported in OSB 12c, To my knowledge OData is a standard that defines to build and consume REST services. Will it be supported in current OSB release? I tried creating one REST reference and test it by hitting one public service URL which is build up on OData : GET http://services.odata.org/v4/TripPinServiceRW/People. This results in error in business service, which made me think whether OSB supports this protocol.

Any help or pointers over here?

Regards,

Vaibhav

Hi Vaibhav,

just created a business service pointing to http://services.odata.org/v4/TripPinServiceRW/People. After running the business service from JDev I can see the following error: "REST Business Service returned HTTP response with status 302." saying that I have to redirect to http://services.odata.org/v4/(S(2bcr10wb1l5mupgxs3oy3buh))/TripPinServiceRW/People. I am not an expert in OData format and protocol, but it looks like a security or session identifier the string in the brackets (S(2bcr10wb1l5mupgxs3oy3buh)).

If you try to create a business service and in the target URL this code is present then you can successfully invoke the service and get the JSON response encoded in SOAP. Hence, use it further in message pipeline processing.

The solution here is to enable the business service to follow HTTP redirects if you do not want to hardcode that key/identifier in your target URL.

To enable a business service to follow HTTP redirects check the documentation - https://docs.oracle.com/cd/E23943_01/dev.1111/e15866/http_poller.htm#OSBDV951 . It works for 12c as well.

I used 12.1.3 and works fine. In 12.2.1 you have native support for REST, i.e. the REST is not internally and always converted to SOAP so the solution should work there as well.

HTH,

A.

Thanks Anatoli, you are right , somehow i missed '302' error code as i was more more eagerly looking at Odata. I believe there is no need for a separate support for OData as these are RESTFul APIs only.
