Debian java japanese input method and display problem

Hi there everyone,

My name is David Marceau.  I am researching how to develop a java gui that is
multilingual and that accepts japanese character input.  How do I make Debian
java jdk1.5 accept japanese character input and properly display these in a java
gui components(i.e. textarea/combobox...)?

I am using:
-Debian unstable version
-Debian is configured japanese EUC-JP.
-Debian keyboard input for japanese works via "kinput2 -canna" with mozilla and
openoffice with no problems.

Here is how I installed jdk1.5 with debian unstable:
# in order to have make-jpkg, you need to install the virtual package
# "java-package".  You need to download the jdk15.bin file from sun.
# Then you create a .deb/knoppix package with this.
fakeroot make-jpkg jdk-1_5_0-linux-i586.bin
dpkg -i sun-j2sdk1.5_1.5.0+final_i386.deb
apt-get install sun-j2sdk1.5debian

#once it is installed
#the command lines aren't pointing to the new 1.5 tools
# you need to do the following
update-alternatives --config java
update-alternatives --config javac
update-alternatives --config serialver
# there are many other jdk command-line tools that need to have
# their alternatives changed to point to the 1.5 bin path
# update-alternatives --config serialver
# There are 3 alternatives which provide `serialver'.
#   Selection    Alternative
# -----------------------------------------------
#  +    1        /usr/lib/j2se/1.4/bin/serialver
#       2        /usr/bin/serialver-cp
# *     3        /usr/lib/j2sdk1.5-sun/bin/serialver
# Press enter to keep the default[*], or type selection number: 3
# Using `/usr/lib/j2sdk1.5-sun/bin/serialver' to provide `serialver'
# Do this update-alternatives dance to all the jdk tools you need to use.
# If you don't you will come up with
# some funky errors you won't know where they came from

cd jdk1.5.0/demo/jfc/Font2DTest
java -jar Font2DTest.jar
When I select "USER TEXT" in the range combo box, a popup textarea dialog is
shown.  When I do shift+space to enter japanese input method mode, the
characters I type display square gray blocks as opposed to true  japanese
THAT IS THE PROBLEM...it doesn't display what I type properly.

NOTE:  Below the improperly displayed text is an update button that takes what I
typed in the user text box and draws this into the main dialog's font canvas.
Surprisingly when I press the update button, the main dialog's font canvas
displays the hiragana/katakana/kanji properly while the user text dialog's
characters still display my input with square blocks???

I am aware of
and I tried putting them in the jre/lib/ext directory but I didn't see any
changes. It still displayed square blocks when I type in japanese input mode.
That said I didn't see the expected input method menu in the window's command
button displayed.

Any help in this matter would be greatly appreciated.  Thank you for considering
my request.

どうぞ よろしく おねがいします、
