    Hi,

    Errror message bad major version tell us that you are running a JDBC Driver version compiled to higher java version than the one that you are running with your application server, for example, if your application server is running with Java 7 and you are using ojdbc8.jar that is compiled to run with Java 8 you will find those errors. Be sure to use a JDBC Driver compatible with java version your application server runs.

    Regards,

    Márcio d'Amico.
