Installing Java 1.5

This information provides the four steps I used to install Java. The browser is a backported Firefox 1.0.

How to install Java on Ubuntu Linux with four commands

Add these two repositories to /etc/apt/sources.list

deb ftp://ubuntujava.yimports.com/ binary/
deb-src ftp://ubuntujava.yimports.com/ source/

And execute these commands:

% apt-get update
% apt-get install java-ubuntu sun-j2sdk1.5.0

You must enable the Universe repository for this to work

I just wanted to make sure you are aware that you are breaking your Sun license agreement by distributing this software. I do hope nobody tries to take you to court for it. I also want all of your users to be aware that they are only granted rights to use this software if they accept the Sun license agreement as listed on www.java.net.

A much cleaner solution is to install java-package out of the multiverse, download the .bin file of the jre or jdk from Sun yourself and then run make-jpkg on the bin file to create a deb.

Jerry - These packages show the Sun licenses and require acceptance before they will install. The only legal problem is that of distribution.

None of above worked in 5.04/Hoary / i386 for me, but a helpful soul on IRC gave me this: Add deb ftp://ftp.tux.org/java/debian/ sarge non-free

to /etc/apt/sources.list

and then do

apt-get install j2re1.4 java-common

a complete description for newbies is here:

Installing Sun's Java on Hoary (expanding on Gabriel Bauman's comment from above)

Download Sun's JDK (.bin format) from http://java.sun.com/j2se/1.5.0/download.jsp. Choose either the JDK or JRE link. Execute these commands (assuming you downloaded the file 'jdk-1_5_0_02-linux-i586.bin'):

% sudo apt-get install java-package fakeroot
% fakeroot make-jpkg jdk-1_5_0_02-linux-i586.bin
% sudo dpkg -i sun-j2sdk1.5_1.5.0+update02_i386.deb

Test installation:

% java -version
java version "1.5.0_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_02-b09)
Java HotSpot(TM) Client VM (build 1.5.0_02-b09, mixed mode, sharing)

The "/java-web-start.applications: Permission denied" messages can be ignored when building the package. The above also works with jdk-1_5_0_03-linux-i586.bin under Hoary. -- rcs 07-May-2005

Installing Sun's Mozilla (-Firefox) Java Browser Plugin on Hoary

% sudo ln -s /usr/lib/j2re1.5-sun/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla/plugins/
% sudo ln -s /usr/lib/j2re1.5-sun/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla-firefox/plugins/

Restart the Browser and check with about:plugins in the Browser's URL-Field, whether the plugin has been recognized.

Another way to check the java installation is the "Test your Java Virtual Machine (JVM)" page at http://www.java.com/en/download/help/testvm.xml. If you want to use the browser plugin after installing the JDK, use the commands above with /usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7/ as the path instead. -- rcs 07-May-2005

The path to libjavaplugin_oji.so should be

% sudo ln -s /usr/lib/sun-j2re1.5.0/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla-firefox/plugins/

For those who followed the earlier assumption that the JDK was downloaded, the correct symlink statements for the Java Plugin are:

% sudo ln -s /usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla-firefox/plugins/
% sudo ln -s /usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla/plugins/

I managed to follow the instructions of downloading the JDK, packaging the JDK, and then depackaging the .deb file. Everything worked according to plan except the last part where I had to install the plugin for Firefox. The 1.0.4 I have installed in my home directory and the soft link has to be created in the Firefox directory. My solution is:

% sudo ln -s /usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so <firefox directory>/plugins/

Hope this help...

After upgrading to mozilla-firefox 1.0.4~5.04ubp1+1.0.2-0ubuntu1, I lost the use of my Java plugin. I also had installed sun-j2re1.5 and sun-j2sdk1.5. This is what I did to restore functionality:

1. ls -al /usr/lib/mozilla-firefox/plugins/libjavaplugin.so

gave

lrwxrwxrwx 1 root root 39 2005-06-06 17:00 /usr/lib/mozilla-firefox/plugins/libjavaplugin.so -> /etc/alternatives/firefox-javaplugin.so

This was a broken symlink.

2. ls -al /etc/alternatives/firefox-javaplugin.so

gave

lrwxrwxrwx 1 root root 58 2005-06-07 01:47 /etc/alternatives/firefox-javaplugin.so -> /usr/lib/j2sdk1.5-sun/plugin/i386/ns7/libjavaplugin_oji.so

3. cd /usr/lib/j2sdk1.5-sun/plugin/i386/ns7/

gave

bash: cd: /usr/lib/j2sdk1.5-sun/plugin/i386/ns7/: No such file or directory

4. dpkg -L sun-j2sdk1.5 | grep libjavaplugin_oji.so

gave

/usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7-gcc29/libjavaplugin_oji.so

5. Conclusion: the directory jre, sandwiched between j2sdk1.5-sun and plugin was missing.

6. Solution:

sudo ln -sf /usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so /etc/alternatives/firefox-javaplugin.so

7. If you wish, you can also

sudo ln -sf /usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so /etc/alternatives/mozilla-javaplugin.so

and

sudo ln -sf /usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so /etc/alternatives/netscape-javaplugin.so

8. Check that symlinks are not dead; restart mozilla-firefox, type
