I am looking to implement WS Security with OSB for one of our customers, so on doing a quick search the following articles caught my eye.
Will be looking at some of these before I decide what would work best for my situation, or whether I need to come up with a new approach all together.
Well on further investigation it seems OWSM is the only way forward as the WS-Policy will be deprecated from 12c.
