oracle oci connection-entry point kpufhndl0 could not be located

[Asher Tarnopolski]

hi, a question for those of you working with oracle tools.

i try to connect to oracle's db from jdeveloper.
a thin connection works fine, but i have to use an oci connection which i fail to set.
i've edited jdev.conf file as described here: http://www.oracle.com/webapps/online-help/jdeveloper/10.1.2/state/content/navId.4/navSetId._/vtTopicFile.db%7Ccdb_rconnectionreqsoci~html/
and added AddNativeCodePath pointing to oracle installation directory.
but an attempt to test a connection returns an error saying "The procedure entry point kpufhndl0 could not be located in the dynamic link library OCI.dll".
any thoughts?
thanks a lot!
