Help installing Java onto Linpus Linux

[spitfirejoe]

Hi i have an Acer Aspire One running Linpus Linux Lite v1.0.21.E and i am having issues with installing Java to the point where it's driving me mad. I want to play Runescape, but the aplett does not initialize. Ive seen numerous guides on how to install it but none of them are clear enough! I am new to Linux so its hard . Could somebody please explain, in depth, how to install Java and get Runescape Working. Thanks.

Assuming your using firefox (or mozilla based browser) and in a 32 bit environment (there's no 64 bit applet support at the moment).

1. Download the JDk/JRE from Developer Resources for Java Technology (eg. jdk-6u18-linux-i586.bin)

2. chmod 755 jdk-6u18-linux-i586.bin

3. mkdir -p /opt/java

4. cd /opt/java

5. Run the downloaded java file (from step 1), will create a directory (jdk1.6.0_1 containing java

6. ln -sf jdk1.6.0_18 jdk

7. cd /usr/lib/mozilla/plugins

8. ln -sf /opt/java/jdk/jre/plugin/i386/ns7/libjavaplugin_oji.so .


Start firefox and type "aboutlugins" (that should read "about colon plugins") in the location bar. You should see java as a plugin.

Works on all linux dist's I've used.

[user@localhost Desktop]$ chmod 755 jre-6u18-linux-i586.bin
[user@localhost Desktop]$ mkdir -p /opt/java
[user@localhost Desktop]$ cd /opt/java
[user@localhost java]$ ln -sf jdk1.6.0_18 jre
ln: cannot remove `jre': Permission denied
[user@localhost java]$ cd /usr/lib/mozilla/plugins
[user@localhost plugins]$ ln -sf /opt/java/jdk/jre/plugin/i386/ns7/libjavaplugin_oji.so
ln: cannot remove `./libjavaplugin_oji.so': Permission denied
[user@localhost plugins]$

Well thats what happens, you say 'run' the file, when i click on it it asks me to install a patch which doesn't exist. So i have to just continue from there. Also i dont see the Java plugin.
This however is the furthest ive got yet, so thanks. Pointers of where im going wrong would be great.

You need to root. andn run the file from a command session with the "/opt/java" as your working directory.

eg.

open a xterm/terminal as root (sudo xterm ???)

then complete commands 2 onwards in that terminal.

Note with line "ln -sf jdk1.6.0_18 jre" replace "jdk1.6.0_18" with whatever directory the installer created.

I think i know how to finally get it to work. How do i find the directory that the installer created? Sorry if i seem an absolute noob but ive never used Linux before in my entire life .

It's created under your current working directory (it is with the JDK, which is what I usually install).

So if you did "cd /opt/java" before you ran the installer, then the directory should be under "/opt/java".

[spitfirejoe]

ive found the directory, its just an icon labelled 'jre'...?
