java runtime -No applets displayed

I cannot get a java runtime environment to work properly under the 
debian-live cd.
I cannot get the applets to display.
I will list how far I have got but feel I'm actually going about this 
the wrong way.
I have google'd these lists (and generally) but not found an answer.

I re-master Knoppix OK and my jre settings work OK under konqueror and 

I am using lh_config version 1.0.5-1 and my build line is:
  lh_config -d lenny -a i386 -p "kde-core 01_package_add" 
  -b net --net-root-path /nfsroot2 --net-root-server --
net-tarball none|gzip 
  --bootapend-live "locale=en_GB.UTF keyb=uk timezone=Europe/London"

By trial and error I found that by copying j2re-1_4_2_13-linux-i586.
bin into <build dir>/config/chroot_local-hooks
the package is installed into my live-cd root under the directory 
As an aside I would really like to 
Q1 -install it into /usr/java/j2re1.4.2_13 and 
Q2 -I would like my script to auto-answer the licensing questions (ie 
quit + yes)
Hence my concern that this is not the intended way to install a jre.

My autostart file have these lines:
sudo ln -fs /j2re1.4.2_13/bin/java /usr/bin/java
sudo ln -fs /j2re1.4.2_13/bin/java_vm /usr/bin/java_vm
sudo ln -fs /j2re1.4.2_13/plugin/i386/ns4/libjavaplugin_oji.so 
sudo ln -fs /j2re1.4.2_13/plugin/i386/ns4/libnullplugin.so 

Q3 -Could I transfer these line into a hook script?

Upon boot if I type:
# java -version 
java version "1.4.2_13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_13-b06)
Java HotSpot(TM) Client VM (build 1.4.2_13-b06, mixed mode)

When I goto say: opera.com/media/applets/clock and do not get the 
clock applet.
I set up java under konqueror via this link: http://www.konqueror.
And it does all work under my knoppix re-master. I have duplicated the 
setup under opera with the same result.

Q4 - Am I missing some additional packages required by java?

Although I believe I require version j2re1.4.2_13 for HP Proliant iLO 
cards I am willing to try other versions.
I note that these are available via apt-get update:
  default-jre - Standard Java or Java compatible Runtime
  default-jre-headless - Standard Java or Java compatible Runtime 
  openjdk-6-jre - OpenJDK Java runtime, using Hotspot JIT
  openjdk-6-jre-headless - OpenJDK Java runtime, using Hotspot JIT 
  openjdk-6-jre-lib - OpenJDK Java runtime (architecture independent 

My concern here is that that they appear to want a lot of disk space 
upto 165MB. I would appreciate any 
user feedback on using any of these under a debian-live build and how 
to set them up.
