I've done this with Personal Java (soon to tbe Personal Profile). It may or may not be possibile under MIDP and PDAP. This is covered by the JAM, which is woefully underspecified. Particular vendor implementations may or may not allow it.

In MIDP 1.0, you can't use classes that you download dynamically.
You can download images or sounds and store them in RMS (although you can't play the sounds in MIDP 1.0).

When you create an app, you provision it onto the MID, PDA, or other device, using a vendor specific system--usually through the cradle. The application then is resident on the device and can be run locally, even when not wired to any other device.
Some devices will support OTA (over the air) provisioning. My last companby allowed the product to be updated wirelessly.
But all this is vendor specific.
