Howto install Sun Java Runtime Environment (JRE) in Ubuntu 10.04 (Lucid Lynx)

Java is an object-oriented programming


language developed by Sun Microsystems in the early 1990s. Java
applications are compiled to bytecode, which at runtime is either
interpreted or compiled to native machine code for execution.

The language itself derives much of its
syntax from C and C++ but has a simpler object model and fewer low-level
facilities. JavaScript, a scripting language, shares a similar name and
has similar syntax, but is not directly related to Java.

We have already posted about sun java was moved to the Partner repository in Ubuntu 10.04 (Lucid)

Procedure to follow

Open terminal and run the following commands

Add partner repository using the following command

sudo add-apt-repository “deb http://archive.canonical.com/ lucid partner”

Update the source list

sudo apt-get update

Now install sun java packages using the following commands

sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts

The above command will download all the required packages and begins
the installation, you’ll get a screen that contains the Sun Operating
System Distributor License for Java and hit Enter to continue.

You’ll see a dialog that asks you if you agree with the DLJ license
terms. Select Yes, and hit Enter; the JRE will finish installing.

Testing Java Runtime Environment

You’ll want to confirm that your system is configured properly for Sun’s JRE. This is a two-step process.

First, check that the JRE is properly installed by running the following command from a terminal.
