[CentOS] httx, iiimf, and Japanese input still not working

Japanese input - the final frontier. This is the last obstacle before I 
can work completely within Centos and be free of Windows.
But it's still not working.

To cut to the chase, in my quest to get Japanese working, I came across 
the following:
https://www.redhat.com/archives/fedora-i18n-list/2004-November/msg00030.html
... where someone says:
"You need to have httx (htt_xbe) running to use iiimf in KDE."

Okay, so I go looking on the net for httx, but can't quite figure out 
what it is or how to download it.

So my question is what is it, where do I get it, and will it help me get 
Japanese input?

Now, for anyone who needs a reference, what follows is how I came to 
find out about httx.

I was following the instructions on this page:
http://fedora.redhat.com/projects/i18n/iiimf-faq.html

And here are the results of some of the commands they suggest to check 
if iiimf is running in KDE:

[root at localhost dave]# service iiim status
htt (pid 3193) is running...

[root at localhost dave]# rpm -qa |grep iiimf
iiimf-csconv-12.1-13.EL
iiimf-protocol-lib-11.4-43

[root at localhost dave]# ps auxwww | grep httx
root      4433  0.0  0.2  5272  664 pts/4    S+   18:38   0:00 grep httx

[root at localhost dave]# LANG=ja_JP.UTF-8 XMODIFIERS=@im=htt kedit
QInputContext: no input method context available
QInputContext: no input method context available

When I went to Google to look up this error, that's when I eventually 
came across httx, but that's where I was stonewalled.

I hope someone can help me get this last piece of the puzzle in place.
