[JNI-LAYER] Could not find server function

Hi there,
I’m working on a service call from SAP and I’m getting the error “[JNI-LAYER] Could not find server function” when launching the program.

The funiest is that it works on one of our other SAP system without probs (regardles of SAP version) …

i’ve checked all features needed to to this kind of connection and it SEEMS ok.

Could anyone tell me what to check or do to fix that …???
