Oracle Weblogic Server My doubts about drupal requirements are:
- Can run Drupal 7 on a Oracle WebLogic Server? How would the integration be?
- Can i use the Oracle driver for this porpuse?
Yes you have to use Oracle Driver.


  This is a driver that allows Drupal to use an Oracle Database instead
  of MySQL as the primary backend.
