Prova a scartare la connection oggetto come questo:
Context ic = new InitialContext();
DataSource ds = (DataSource)ic.lookup("jdbc/OracleDS");
Connection conn = ds.getConnection();
if (conn.isWrapperFor(oracle.jdbc.OracleConnection.class)) {
// Returns an object that implements the given interface to
// allow access to non-standard methods, or standard methods
// not exposed by the proxy.
oracle.jdbc.OracleConnection oraCon = conn.unwrap(oracle.jdbc.OracleConnection.class);
// Do some Oracle-specific work here.
oraCon.setReadOnly(readOnly);
....
}
conn.close();
