Please have a look at the following code. I have made
use of the oracle  thin Driver. This ships with oracle
itself and this the driver that you should be using.
If you need to go through JDBC-ODBC bridge you need to
create a DSN etc etc...

This hsould provide you with ideas of how to call a
stored proc with in and out parameters.
