Ich habe wahrscheinlich eine Antwort auf answers.sap finden können. Damit gibt es ein Problem: ich kann die leider nicht nachvollziehen. Könnte jemand die Antwort in eine einfachere Sprache und ins Deutsche übersetzen? Danke!
"Hi,
you can have multiple clients in an XI system but only one can keep the role of the Integration Server. All other clients may act as application systems (most probably not done in reality).
In a double-stack installation the J2EE engine is always connected to one client in the ABAP system. In a XI system this is always the client where the Integration Server is running.
The reason why there is no client conecpt in a J2EE engine is that only java applications are running there. There are no tables containing business data as we know this from ABAP.
Hope this helps,
Juergen"
