Tizen SDK on Ubuntu only supports Oracle's Java implementation opposed to OpenJDK which is the one that it ships with preinstalled. The instructions below are how I installed Oracle Java. There are other methods but this one worked well for me.

The instructions below provide a guide to install the official Oracle JDK 6. You will need to regularly update this manually to ensure your installation maintains recommended security and stability fixes.

Install the Oracle JDK 6

Oracle themselves have the official guide to install their JDK - below is based upon those instructions.

  • Download the 32bit or 64bit Linux "compressed binary file" - it has a ".bin" file extension
  • Give it permissions to execute and extract it

    chmod a+x [version]-linux-i586.bin

    ./[version]-linux-i586.bin

During installation it will ask you to register - press ENTER. Firefox will open with the registration page. Registration is optional.

JDK 6 package is extracted into ./jdk1.6.0_x directory, for example ./jdk1.6.0_30.

Lets rename it:

mv jdk1.6.0_30 java-6-oracle 
  • Now move the JDK 6 directory to /usr/lib

sudo mkdir /usr/lib/jvm

sudo mv java-6-oracle /usr/lib/jvm

switch to Oracle JDK 6

webupd8.googlecode.com hosts a nice-easy script to help with this.

wget http://webupd8.googlecode.com/files/update-java-0.5b chmod +x update-java-0.5b sudo ./update-java-0.5b 

don't worry - 0.5b refers to the script version - not the version of java!

An alternative to this is to use the webupd8 ppa and the update-java package.
 
install-Oracle-JDK 6
 
Finally test the switch has been successful:

java -version javac -version 

These should display the oracle version installed - 1.6.0_30

Install the Firefox/Chrome plugin

In a terminal:

mkdir ~/.mozilla/plugins 

Remove the IcedTea plugin, if it has been installed.

sudo apt-get remove icedtea6-plugin 

Remove a former version of the Java plugin (may or may not be present)

rm ~/.mozilla/plugins/libnpjp2.so 

Now you can install the plugin, by creating a symbolic link (you tell Firefox, where the plugin is located).

(32bit)

ln -s /usr/lib/jvm/java-6-oracle/jre/lib/i386/libnpjp2.so ~/.mozilla/plugins/ 

(64bit)

ln -s /usr/lib/jvm/java-6-oracle/jre/lib/amd64/libnpjp2.so ~/.mozilla/plugins/ 

Confirm that the JRE has been successful by using the official oracle website.
