Jdbc driver & charset problem

Question

The charset of my oracle database is ISO8859p15.
SO I need to add nslcharset12.jar in my classpath.
In a servlet engine like Tomcat or Resin I MUST add this jar to the startup script of the servlet engine. But with Oracle IAS, I'm not able to install it.
I try to add the jar in the WEB-INF/lib of my webapps, I try to replace the jar in the ORACLE_HOME/jdbc/lib, I try to put it in ORACLE_HOME/lib but I receive allways an exception during database query like :
- UNKNOWN CHARSET ID 46
- Class violate classloader loading.
I have the same behavior under Weblogic.
What is the correct way to install this jdbc driver(I try oci & thin connection).

391347,
More recent versions of OC4J (stand-alone) use the "j2ee/home/applib" subdirectory for extra JAR files.
On my OC4J 9.0.4 installation, there is a "readme.txt" file in that subdirectory. Here are its contents:
This directory should be used to place common jar files,
and they'll be loaded by default and will be available to
all j2ee applications deployed to this OC4J instance.Note, however, that OC4J can be configured to use a different directory. The default configuration uses the "applib" subdirectory, so if you have not changed the default configuration, putting your "nslcharset12.jar" file in that directory should work.
Good Luck,
Avi.
