Why having two engines and two schemas (Java, ABAP) ?

[Former Member]

Hi there,

I am a beginner in the world of Java for SAP. I am reading and reading loads of documentation (from SAP Help and SDN) but still feeling a little bit lost. Maybe you can help me with these conceptual doubts, by briefly explaining the matter and/or pointing to suitable documentation. I apologize if you feel my questions are naive.

1. Are both ABAP and J2EE engines intended for the same purpose? If not, which are the differences? If they are, why having two engines?

2. Each of the engines have their own schema. I guess this means that data are not directly shared, but just by means of BAPIs or RFCs, making it look pretty much like two completely remote and different systems. Why this approach? Where is the advantage?

Thanks in advance and kind regards.

Antonio Sánchez.
