came across this method on another forum website...

http://www.wapHQ.net and upload the .jar java file, actually no need for the .jad file.
since the java files are small it'll take no time to upload.
the next page will tell you to aim your mobile phone's browser to
www.waphq.net and to punch in a given ID number (6 digits) and click FIND FILE.
it'll take you to your java file that you've uploaded and hit download file link and of course Behold will automatically download and install the game under your apps

tried this with two free java games, starting with a simple Jetris (tetris clone) to an RPG game and both installed with no problems

no risk of bricking your Behold and having to go through all the trouble of refreshing java applications list.
