Java 6 install

Ubuntuers -

I'm switched my Linux flavor from Fedora to Ubuntu and am have a few issues finding packages. I installed Java 5 which went well using the command

sudo apt-get install sun-java5-jdk

I decided to go ahead and bite the bullet for Java 6 but couldn't find a java 6 package. Here are the steps I used to install.

download java from http://java.sun.com/javase/downloads/index.jsp
cd to dowload directory
chmod a+x jdk-6-linux-i586.bin
sudo ./jdk-6-linux-i586.bin
sudo mv jdk1.6.0 /usr/lib/jvm/
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.6.0/bin/java" 1
sudo update-alternatives --set java /usr/lib/jvm/jdk1.6.0/bin/java
java -version

Is the the 'normal' way or is there a package out there I could have installed?

No packages yet (for either Dapper or Edgy), so you did the right thing, I think. The alternative would be to install Feisty three months before its release (and I'm not sure that has jdk6 atm).

I dig your (Sun's) method. That's how I do it, and it's how many of us recommend doing it. There are packages out there though - all prepared by third parties.

Get the bin file from their site, extract it, move it to something like /opt/ and add these to your ~/.bashrc: (with the right path where mine mentions /opt/)

export JAVA_HOME=/opt/jdk1.6.0
export PATH=${JAVA_HOME}/bin:${PATH}

You can actually do it that^ way to any path. I often leave the Java folder on my desktop. The reason you might move it to /opt, or, /usr/lib, is to included it into your update-alternatives config.

You left that out. You should really include those instructions.

Or because I don't like directories cluttering my desktop or home folder and being accessible without root privileges. So I move all important executable stuff to /opt/ or /usr/bin/.
And what's the advantage of including it in the update-alternatives path? I've just set the env var and I'll most likely not touch it again until a new java version is released.

lol Normally, I'm saying the things you say. I hardly ever configure update-alternatives. Some users like it though, because they mix techniques for installing Java programs, and some of them rely on there being an active (and current) configuration in alternatives. That's all.

Just for future reference sun-java6-<bin, jdk, plugin, source, etc> are in the multiverse repository. You can enable is with the graphic interface in Synaptic or Adept, or by editing your /etc/apt/sources.list. Make a backup first.

You can see an example of that in the Ubuntu Customization Guide in the Third Party Projects section. There are examples there for Dapper (6.06) and Edgy (6.10).

You're way behind. Most of the developers who play in the forums download Java right from Sun. I was being playful in this thread, but I wrote a tutorial that sums up Sun's method. Downloading the packages from the multiverse is okay too, but it isn't necessary. Java isn't an Ubuntu program, obviously, so no need to rely on Ubuntu to get it.

Java
eclipse
Tomcat
LimeWire
Open Office

They're just too easy to download. Everything except Java can simply be extracted anywhere you please. Configuring update-alternatives is a snap.

I was just pointing out that it's indeed in the repositories. Some of us are crazy and like package management.
