I feel your pain. WEME/j9 is kind of a pain about the fact that it has no support for JSR 82.
The quick answer, as I got a few months ago, is that it's not really possible, per se, to 'buy' a BT API to plug in to WEME. However, I believe there are some vendors who are selling modified versions of WEME or other CDC/CLDC environments that have integrated a JSR-82 compatible solution, so you might just do a search to see what you can find. (A quick google search turned up aventanaBlueTooth and avelink as promising-looking products.)
WRT generating a barcode - I imagine there has to be a way to generate the image, though I'm not, off the top of my head, coming up with any method. (I'd think you probably would want to lean towards a CDC implementation of Java ME if you're going to do this, though - I don't know, but I'd lean towards saying CLDC lacks the tools to handle this.)
