Create a REST pass through in Oracle Service Bus (OSB) 12c. Clear explanations and detailed steps. Would be useful for beginners

1. Create REST pass-through
service in OSB

2. Create the REST provider
reference Business Service

3. Important!!

4. REST service base address
REST service Resource and
parameter

5. Edit the REST service
Resource and parameter
Request parameter

6. Operation name
HTTP method
Request parameter
automatically added

7. Request parameter
details. No need to change
now

8. Response require a
schema. Press the button
to create it from Json
sample
Response payload Json

9. Just “Next”

10. Name and folder of the
schema file

11. Choose this to create from
Json sample

12. Paste the Json sample
from REST provider
response
Just “Next” at the end

13. The schema
Just “Next” at the end

14. Just “Finish” at the end

15. Response with the new
schema

16. The Business Service after
all “Next” and “Finish”

17. If you open the Business
Service you will note the
“Expression”. Can be
useful in advanced use.

18. The shortcut to expose
the exposed service

19. The exposed service name

20. The exposed service is almost a
copy of the REST provider
Business Service but still need to
be edited. To make it similar to
the parameters, resource path

21. The exposed service resource
path

22. Open the exposed service
operation to edit

24. The Request parameter
adjustment

25. Check Json or XML as you wish.
Note that the schema is the same
as the REST provider.

26. Final look and “Finish”

27. Project ready for testing

30. First test the REST provider Business
Service. If this does not work, no need to
continue. You have a big problem

33. Now, test the new exposed REST service

35. The fast way is normally too simplistic.
That is why we need a pipeline

37. Uncheck!!! And press the WSDL selection
Why WSDL and not REST? Probably
because WSDL is the way OSB handles any
internal interaction

38. Note it is the same WSDL as the REST
provider

40. Connect the elements and save.

41. This is the pipeline ready for more
complexity

42. Thank you!
