I don't use ODP (I use the Microsoft drivers) but it might not matter because ODP is only the technology that gets the data into your app, not the binding part of it.
Read the DW2 link in my signature, section: creating a simple data app
And simply modify the advice given, to use your oracle DB
Then you'll have to go the extra step of converting the tableadapters to use ODP. I wouldnt bother
