Oracle Apps 11i connectivity

What is the best way to integrate Oracle Apps 11i. Does wM have an Oracle Apps adapter or should one use the Oracle(I) adapter.
How hard/easy is it to interface using the Oracle (I) adapter.

webMethods Enterprise doesn’t have Oracle Applications 11i Adapter.At this moment you have to use Oracle (I) adapter to integrate with Oracle Applications 11i. I think it is not such a difficult job to develop the interface with Oracle (I) Adapter.

Are there any design documents that you guys can provide me for wm Enterprise integration with Oracle Apps 11i
