I have also run a few times utlrp.sql and still nothing, i dont know anymore what to do


loadjava -schema TEST directjava.jar

If OCI8 is really being used, you need to realize that SQL*Net only works between Oracle versions within TWO major releases.
So I am surprised when you report OCI8 worked with V11 DB, but am not surprised that it does not work with V12 DB.

Hi
the issue has been fix it was invalid objects in the database, here is what i did to fix it

sqlplus / as sysdba
@?/rdbms/admin/catproc.sql
@?/rdbms/admin/utlrp.sql
@?/rdbms/admin/utlrp.sql
@?/rdbms/admin/utlrp.sql

>> The utlrp is meant to be executed few times in case there is any dependency that needs to be resolved.


Please login as sysdba and run the below commands, so the validation check in catnojav.sql will pass, so a complete JVM removal can proceed.

sqlplus / as sysdba
execute sys.dbms_registry.loaded('JAVAVM');
execute sys.dbms_registry.loaded('CATJAVA');
execute sys.dbms_registry.valid('JAVAVM');
execute sys.dbms_registry.valid('CATJAVA');


reload JVM using below note:
