Installing Sun JDK 6 Update on Ubuntu 12.04

1. Download the jdk-6u32-linux-i586.bin from the Sun Java Download Centre. If you are on 64-bit Ubuntu, you should grab jdk-6u32-linux-x64.bin.
2. Make the bin file executable:

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

3. Extract the bin file:

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

4. Move extracted folder to this location:

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

5. Install the new Java source in system:

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

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

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

6. Choose default Java:

   1	sudo update-alternatives --config javac

   2	sudo update-alternatives --config java

   3	sudo update-alternatives --config javaws

7. Check the Java version:

   1	java -version

8. Verify the symlinks all point to the new Java location:
