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.
Oracle themselves have the official guide to install their JDK - below is based upon those instructions.
chmod a+x [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
Lets rename it:
mv jdk1.6.0_30 java-6-oracle
sudo mkdir /usr/lib/jvm
sudo mv java-6-oracle /usr/lib/jvm
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
Finally test the switch has been successful:
java -version javac -version
These should display the oracle version installed - 1.6.0_30
In a terminal:
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)
Now you can install the plugin, by creating a symbolic link (you tell Firefox, where the plugin is located).
ln -s /usr/lib/jvm/java-6-oracle/jre/lib/i386/libnpjp2.so ~/.mozilla/plugins/
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.
