Oracle XE makes it really easy to export your database schema.
Go to the Oracle XE web interface (running on http://localhost:8080/apex/ by default), and login with your username (not the system user).
Choose Utilities -> Generate DDL. Check the tables for which you want to export the DDL commands, and you are good to go.
