Java Database Connectivity (JDBC)

Hi,

i have downloaded the latest JDBC drivers (10.2.0.1.0).

I am trying to use them in a web application that i deploy to Sun One Application Server 8.1.

When i try and get a connection, I get the following error:

java.lang.SecurityException: Sealing violation loading oracle.sql.BlobDBAccess : Package oracle.sql is sealed.

I did a search and found references here and on the Sun site about possible duplicate jars/classes.

I could not find any duplicates so as a test I swapped the ojdbc.jar with an earlier version (from the 9i range) and everyhting worked!!!!!

Whats going on? My database is 9i but i was under the impression that the latest 10g drivers were backwards compatible.

Thanks
