1) Go to the ["J2RE"] download page
2) Select the Linux self-extracting file
3) Save it to a suitable location (eg /tmp)
4) Move it to the path you want to run it from (eg /usr/local)
#mv j2re* /usr/local/
and change to this directory:
#cd /usr/local
5) Run it - as root #sh j2re-1_4_1_01-linux-i586.bin
6) This will prompt you for a licence agreement. Accept it
7) It will then create a folder j2re1.4.1_01/
8) Then, in your mozilla plugin directory (eg /usr/local/mozilla/plugins) , symlink libjavaplugin_oji.so to the appropriate folder in the j2re folder created above
eg
# cd /usr/local/mozilla/plugins # ln -s /usr/local/j2re1.4.1_01/plugin/i386/ns610/libjavaplugin_oji.so libjavaplugin_oji.so
9) Restart mozilla and test the install - eg go to http://news.bbc.co.uk
10) Repeat the above for your phoenix plugins directory - eg
# cd /usr/local/phoenix/plugins/ # ln -s /usr/local/j2re1.4.1_01/plugin/i386/ns610/libjavaplugin_oji.so libjavaplugin_oji.so
