You might try codebase="/Java/JBox" (preceding slash added). I can not 
remember if the codebase is relative to the .map file or the 
mapserv.exe, but in either case, setting the path relative to the host 
root would be correct given the path to jBox.class that you noted above.

Also look at the source of the page and make sure http://[host][img] has 
been correctly processed. It should look something like 
http://localhost/tmp/xxxxxxxxxxxx.gif
