I have a Java class with APIs that I need to expose them as Web Service operations. Each API has a Input and Output. How to create such a web service using Integrated SOA. I have already built a Web Service using JAX-WS annotations and it works fine. But I would like to know how this can be done using Integrated SOA Gateway? Any examples/documentation would be helpful. I am looking for EBS 12.2 techstack (having WLS).
