Ubuntu 12.04 – install sun jdk 6-7by Cem Ikta • GNU/Linux, Java • Tags: ubuntu 32

Ubuntu GNU/Linux 12.04 LTS (Precise Pangolin) released. I wanted to manuallyinstall the Sun JDK 6 and 7 on Ubuntu.

Installing Sun JDK 6 on Ubuntu 12.04:

Download the sun jdk 6 bin from here.

Make the bin file executeable:

chmod +x jdk-6u32-linux-x64.bin

Extract the bin file:

Ubuntu 12.04 – install sun jdk 6-7 http://www.devsniper.com/ubuntu-12-04-install-sun-jdk-6-7/

./jdk-6u32-linux-x64.bin

Move extracted folder to this location:

sudo mv jdk1.6.0_32 /usr/lib/jvm/

Install new java source in system:

sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_32/bin/javac 1sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_32/bin/java 1sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.6.0_32/bin/javaws 1

Choose default java:

sudo update-alternatives --config javacsudo update-alternatives --config javasudo update-alternatives --config javaws

java version test:

java -version

Verify the symlinks all point to the new java location:

ls -la /etc/alternatives/java*

Enable Java plugin for Mozilla Firefox (even for Chrome)

Installing Sun JDK 7 on Ubuntu 12.04:

Don’t forget javaws in your update-alternatives command:

$ sudo update-alternatives –install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.6.0_32/bin/javaws 1$ sudo update-alternatives –config javaws

# Verify the symlinks all point to the new java location$ ls -la /etc/alternatives/ja*

Thank you, I will probably do the translation and post to my blog thisweekend. I would also suggest you to add jar configuration to your postas it is needed to manually create archives and also to execute somejava programs.

Cem IktaMay 22, 2012 @ 23:46:29

Please check whether you have installed correct 32-bit/64-bit jdk for yoursystem, I have 64-bit installed.Maybe your java file path is wrong? Please check your libs / package /classpath!if everything ok but still error occurs, please try with eclipse or netbeanside, then you can see with eclipse or netbeans better error messages.

Enable mozilla firefox plugin, to reflect even on chrome :32 bit:ln -s /usr/lib/jvm/jdk1.7.0/jre/lib/i386/libnpjp2.so ~/.mozilla/plugins/

64 bit:ln -s /usr/lib/jvm/jdk1.7.0/jre/lib/amd64/libnpjp2.so ~/.mozilla/plugins/

I installed 64 bit version 7 as per all these instructions, I can get Java working inFirefox, but not in Ubuntu 12.04. Java doesn’t show up in the list of programs soI can’t set jar files to open with Java to play Minecraft. When I “search forapplications online” it tells me that it needs OpenJDK Runtime 6 or 7 installed. Ithought Sun’s Java was meant to this job? Any ideas what I’ve done wrong?

hi thanks for the guide, very hepful,But watchout for x86 architecture, the link for the mozilla plugin is :sudo ln -s /usr/lib/jvm/jdk1.7.0_04/jre/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins

Just replace the amd64 with i386
