It seems clear that azureus is trying to run using kaffe binary.
You need java binary. So you need a new path when running azureus.
ie something like

PATH=/home/tilleyrw/downloads/j2re1.4.2_04/bin:$PATH

should do the trick. You can put your path in your .bashrc,
but that will stop kaffe from being default.

So you can run azureus as follows:

PATH=/home/tilleyrw/downloads/j2re1.4.2_04/bin:$PATH ./azureus

or alternatively you can first export the new PATH to your
environment, and then run your app.:

export PATH=/home/tilleyrw/downloads/j2re1.4.2_04/bin:$PATH
./azureus

alternatively you can create a shell script and put either
of the above combinations in that (for a script, I prefer
the latter), Eg the following command sequence is probably
pretty much what you want (I've put spaces between
each command, in case of wrapping, so you can see what
is meant to be on single line...):

cd ~

mkdir bin

cd bin

echo '#!/bin/bash' > azureus

echo 'export PATH=/home/tilleyrw/downloads/j2re1.4.2_04/bin:$PATH' >> azureus

echo '/home/tilleyrw/downloads/azureus/azureus' >> azureus

chmod a+rx azureus

export PATH=~/bin:$PATH

cd ~

echo 'PATH=~/bin:$PATH' >> .bashrc


This will set up your new PATH environment variable
permanently in your .bashrc so that next time you
log in it should all just work. It also exports to
current shell, so it should work in your current shell.

good luck
