I would be very surprised if JJ2+ did work in 98. As you may have seen, we've been having trouble the last couple months trying to get it to run even in Windows XP, which is rather more recent (although equally unsupported by microsoft) than 98. You can try the alternate plus.dll that I linked to in the post above yours and see if that makes a difference, but making something that can run on Windows 98 has not been a priority in a long time, if it ever was to begin with.
