Java 6 update 1 runtime install

Hello amingus,

Follow the steps of this page: https://help.ubuntu.com/community/Java

I did as the directions explained. After finishing I ran java -version.

anthony@Samwise:~$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)

Sun website says I still do not have most current, download Java 6 Update 1....

I am trying to make Pogo.com work for my wife so I can switch her machine over to Ubuntu also. (That will be two more M$ boxes converted....)

I've discovered a method to update Sun Java. The follow is for the Java6 Update 2, but I think it applies to update 1 also.

I tried myself to update from Java1.6.0 to Java 1.6 update 2 (which fixes also a Compiz-Fusion dislplay bug).

The procedure is very simple.

First remove any reference to old java vm using
sudo apt-get remove sun-java*

then donwloading jre-6u2-linux-i586.bin from www.sun.com to your home dir
and execute the following script to install...

sudo mkdir /usr/lib/jvm
sudo mv ~/jre-6u2-linux-i586.bin /usr/lib/jvm
cd /usr/lib/jvm
sudo chmod +x jre-6u2-linux-i586.bin
sudo ./jre-6u2-linux-i586.bin

Now you have a dir /usr/lib/jvm/jre1.6.0_02 and you can also delete jre-6u2-linux-i586.bin file.

Configuring symbolic links to Java update 2.

cd /usr/bin
sudo ln -sf /usr/lib/jvm/jre1.6.0_02/bin/java java
sudo ln -sf /usr/lib/jvm/jre1.6.0_02/bin/java_vm java_vm
sudo ln -sf /usr/lib/jvm/jre1.6.0_02/bin/javaws javaws
sudo ln -sf /usr/lib/jvm/jre1.6.0_02/bin/jcontrol jcontrol
sudo ln -sf /usr/lib/jvm/jre1.6.0_02/bin/keytool keytool
cd /usr/lib/firefox/plugins
sudo ln -sf /usr/lib/jvm/jre1.6.0_02/plugin/i386/ns7/libjavapl ugin_oji.so libjavaplugin_oji.so

Verify if all is OK using command:
$ java -version
results...
$ java version "1.6.0_02"
$ Java(TM) SE Runtime Environment (build 1.6.0_02-b05)
$ Java HotSpot(TM) Client VM (build 1.6.0_02-b05, mixed mode, sharing)

Finaly, edit the file /etc/jvm putting the complete path to java at the top of the list as follow:
$ sudo gedit /etc/jvm

...
# This file defines the default system JVM search order. Each
# JVM should list their JAVA_HOME compatible directory in this file.
# The default system JVM is the first one available from top to
# bottom.

/usr/lib/jvm/jre1.6.0_02 <<<------- new path
/usr/lib/jvm/java-gcj
/usr/lib/jvm/ia32-java-1.5.0-sun
/usr/lib/jvm/java-1.5.0-sun
/usr
...

The Java Control Panel start with "jcontrol". You can create a menu item to do that task.

That's all.
Bye

Thanks for the info I will try this.
