Recently I learned that deploying an ADF 10g application (with 10g ADF libraries) on WebLogic 11gR1 is currently not supported.
I got this from Oracle support in service request 7771680.992 and from Shay Shmeltzer in the OTN forum thread "deploy an ADF 10g application on WebLogic 11gR1".
But, it does not seem to be impossible to deploy this very simple ADF 10g application on WebLogic 11gR1:
