I noticed people were still using my old manual java howto thread. I've since updated the instructions to apply to the newer firefox on dapper.
These manual install instructions should only be used if for some reason you cannot follow the java-package install method. Also,

So, here we go:
=============
First, download the linux runtime installer here. Do NOT get the rpm! Get the one that says Linux (self-extracting file).
After downloading, cd to where you downloaded the file and run:
Code:
sudo mv jre-1_5_0_06-linux-i586.bin /usr/local
cd /usr/local
sudo chmod a+x jre-1_5_0_06-linux-i586.bin
sudo sh jre-1_5_0_06-linux-i586.bin
Say 'yes' to the license agreement and watch it extract the files into a folder called jre1.5.0_06
You're almost done. Now you want to install the plugin for firefox:
Code:
cd /usr/lib/firefox/plugins
sudo ln -s /usr/local/jre1.5.0_06/plugin/i386/ns7/libjavaplugin_oji.so
Firefox is now happily running java applets (once you restart it).
The final steps are:
Code:
sudo ln -sf /usr/local/jre1.5.0_06/bin/java_vm /usr/bin/java_vm
sudo update-alternatives --install /usr/bin/java java /usr/local/jre1.5.0_06/bin/java 1
And now the java runtime environment appears in your list of choices when running 'sudo update-alternatives --config java'! Go ahead and run that, and chose the sun java option. Then to check to make sure it worked, run 'java -version', which should output something like this:
Code:
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_05-b05, mixed mode, sharing)
Done!
If you want to do some configurating with the java control pannel, run
Code:
sh /usr/local/jre1.5.0_06/bin/ControlPanel
Enjoy!
=========================
Removal Instructions
If the time comes when you need/want to remove java, these commands will do the trick if you followed the howto exactly:
Code:
sudo rm /usr/lib/firefox/plugins/libjavaplugin_oji.so
sudo rm /usr/bin/java_vm
sudo update-alternatives --remove java /usr/local/jre1.5.0_06/bin/java
Then you'll want to open up a root nautilus and go to /usr/local/ and delete the jre1.5.0_06 folder.
