JCO Exception handling on ABAP side

Question

Hello Forum,
I am implementing an JCO Server scenario.
I use dynamic repositories like Example7.java from the JCO documentation.
I understand that I need a remote Function module within ABAP, as STFC_CONNECTION exists for the example. This modules act as proxy (method decleration) for the JCO server function to be called. In any other case I will get the "can not find function Exception".
So far right?
Now my question: Example7 throws an JCO.AbapException if anything went wrong, e.g. the function is not implemented.
How to react on this AbapException?
The examples in SAP Help documentation only catch
SYSTEM_FAILURE and COMMUNICATION_FAILURE.
But these are only thrown and catched when something with communication went completely wrong, e.g. RFC not found.
But after the JCO Server was reached and may throw an AbapException while execution: how to catch the AbapException?
Has it to be declared in the proxy?
During execution I can not catch the AbapException and ABAP always generates a short dump.
The dump says:
Exception <JCO_FUNCTION_NAME> (???? why this Exception type)
without message text.
It occurs in the RFC call, of course.
So, how to catch the AbapException in order to avoid the dump?
Can anyone send an example please?
Thanks,
Carsten

Answer 1

you can handle exceptions in workbench. When you select activities a small circle displays on that activity. Drag that small circle and set it to setValue.
so if exception will come that part will be executed and  you can assign an appropriate message(using setValue) to your output variable.
