Hello kevin_ca,
Of course you can discover Bluetooth-enabled devices in J2ME. and This article will help you >> http://www.jsr82.com/forum/index.php/topic,128.0.html .. It contains the complete code for device discovery, service discovery and a lot of codes that will help you..
And about the second question I think that there must be intervention of user.. Such as (Do you accept connection from... and Enter the Pass Code, etc..)..
Hope that I helped you
