How to export a Access Table to Oracle

Hi,
I have a big table in Access containing some records. I need to export them to Oracle database running on the same machine.
The table has only 3 fields. Transaction ID, Customer, Salesman.
How do I send them to Oracle? Do I need to create a table there or something like that? I do not know Oracle.
Is there any simple way to do so? I played around Office 2007, export option but the closest I could get was to export to a text file. My friend said that you can also use this text file as an input in Oracle. But it sounds confusing.
