I used to be able to play runescape on my Acer aspire one until one day i clicked ‘Play now’ and it said i needed to install a missing plugin called Java Runtime Enviroment. I clicked install and immediately after a window came up saying no plugins were installed and gave me an option for manual installation. Ive read on other websites such as http://en.kioskea.net/faq/4731-installing-java-runtime-environment-on-linux these people said that you need a file calledjdk-6u12-linux-i586-rpm.bin BUT i cant find this file anywhere !! Also if u find the download can u tell me how to install it Thanks. Much appreciated and i hope i get back on soon :) ( i use Firefox 3.6)

How do i enable JRE on linux for runescape?

I have downloaded and installed jre-6u23-linux-rpm.bin through terminal but i cant enable it and it never shows up on my firefox addons.the message i get is this
[user@localhost ~]$ su
Password:
[root@localhost user]# cd /usr/lib/mozilla/plugins/
[root@localhost plugins]# ln -s /home/user//jre1.6.0_23/plugin/i386/ns7/libjavaplugin_oji.so
ln: creating symbolic link `./libjavaplugin_oji.so’: File exists
[root@localhost plugins]#

It says i have installed the file but it dosnt show up in firefox addons (the file i downlaoded for firefoxis firefox 3.6.tar.bz2 i dont know if that helped)
Or am i on the completely on the wrong track to get runescape back on my netbook cos all i get is install missing plugins java runtime environment but i already have !! help pleasee ??
