If you have already installed Ubuntu 12.04 you probably have realized that Sun java(oracle java) does not come prepacked with Ubuntu like it used to be , instead OpenJDK comes with it. Here is how you can install Oracle java on Ubuntu 12.04 manually.
- Download jdk-6u32-linux-x64.bin from this link. If you have used 32-bit Ubuntu installation, download jdk-6u32-linux-x32.bin instead.
- To make the downloaded bin file executable use the following command
chmod +x jdk-6u32-linux-x64.bin
- To extract the bin file use the following command
./jdk-6u32-linux-x64.bin
- Using the following command create a folder called "jvm" inside /usr/lib if it is not already existing
sudo mkdir /usr/lib/jvm
- Move the extracted folder into the newly created jvm folder
sudo mv jdk1.6.0_32 /usr/lib/jvm/
- To install the Java source use following commands
sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_32/bin/javac 1 sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_32/bin/java 1 sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.6.0_32/bin/javaws 1 - To make this default java
