You need to know which version of the driver you are using...
The following code shows both driver version and database version:
import java.sql.*;
import java.io.PrintWriter;
public class dbinfo
  public static void main (String arr[]) throws Exception
    PrintWriter outWriter = new PrintWriter(System.out);
    DriverManager.setLogWriter(outWriter);
    String dbDriver="oracle.jdbc.driver.OracleDriver";
    // need to set values for YOUR database
    String dbURL = "jdbc:oracle:thin:@xxxxx:1521:yyyy";
    String dbPW = "zzzzz";
    String dbUser = "zzzz";
    Connection con = null;
    Class.forName(dbDriver);
    con = DriverManager.getConnection (dbURL, dbUser, dbPW);
    DatabaseMetaData dbmd = con.getMetaData();
    System.out.println("=====  Database info =====");     
    System.out.println("DatabaseProductName: " + dbmd.getDatabaseProductName() );
    System.out.println("DatabaseProductVersion: " + dbmd.getDatabaseProductVersion() );
    System.out.println("DatabaseMajorVersion: " + dbmd.getDatabaseMajorVersion() );
    System.out.println("DatabaseMinorVersion: " + dbmd.getDatabaseMinorVersion() );
    System.out.println("=====  Driver info =====");     
    System.out.println("DriverName: " + dbmd.getDriverName() );
    System.out.println("DriverVersion: " + dbmd.getDriverVersion() );
    System.out.println("DriverMajorVersion: " + dbmd.getDriverMajorVersion() );
    System.out.println("DriverMinorVersion: " + dbmd.getDriverMinorVersion() );
    System.out.println("=====  JDBC/DB attributes =====");     
    System.out.print("Supports getGeneratedKeys(): ");
    if (dbmd.supportsGetGeneratedKeys() )
      System.out.println("true");
    else
      System.out.println("false");
    con.close();
}If your driver version is less than 9.2.0.1, the feature is not supported and you need a more recent version of the driver (which you can download from the URL in the previous post). If your driver version is greater than 9.2.0.1, the feature is supposed to be supported and you should contact Oracle support.
