JCO/JCA

Hi all,

I searched for JCO/JCA topics in the forum, but I confused some terms/usages about them. Could anyone clarify for me:

1. What is different between JCO and JCA? Does JCA have the api to programming as JCO? From EP 6, JCO is deprecated, we use JCA to connect to SAP instead, is it right?

2. With JCO, what is JCO Destination, JCO inbound, JCO outbound? When we need to configure JCO Destination?

3. If we develop a portal application (ex: JSPDynPage)/ a WebDynPro application to get data from SAP, do you need configure JCO (in SLD, in EP, ...) or we just need use JCO API in code? How do we configure it?

4. What is Adaptive RFC?
