Good question. I think Metalink is the best place to ask this, as they are the so-called "experts"
Are you using the Forms Servlet to show the Forms in the full application. The biggest issue is can JInitiator work on a J2ME device. I highly doubt it. There might be a way it could work on a PocketPC through their Browser, or maybe a Palm. But definitely not a MIDP 2.0 device. Maybe CDC.
I think it would have to be a product that Oracle provides more than J2ME provides.
