From KC review (so check with Alasdair).

It might be that mostly what's needed is just config examples in the JCA feature doc but as we don't have anything (I think) on JCA yet, it might need something more like an introductory topic at least?

Having taken a look at the JCA topics in the KC:

Those topics are mainly pages and pages of config examples that aren't very interesting or informative to read. It would be more useful I think maybe to write a topic that provides an introduction to what JCA is and why you might choose to use it (otherwise, there's no point reading on). Then, in the JCA feature topic maybe provide some really common, useful simple config examples and link to them from the intro topic. Then in the intro topic, maybe provide some other config examples (maybe slightly longer examples? but not too complicated to follow) and explain what those configurations would do and why you'd do it that way (don't just describe what the attribute and element values are because that's obvious from looking at the example). Don't provide the examples broken down into step-by-step procedures - that's not helpful for configuration.

But start by talking to an SME and asking them what it is and why a developer would use it in a containerised app (it must be in the contains/cloud deployment context). Then find out what the most important things are for the developer to know how to do in order to be able to use it (not all information is equal in value - don't include everything for the sake of it).

This, or some parts, probably have a dependency on #3313 (JMS messaging) because some of it will probably be about connecting to JMS messaging resources.
