Please ensure you have enabled the Ubuntu partner repositories before continuing.

Step 3.1: Install SUN Java 6 Run Time

Type as follows:

apt-get install sun-java6-jre sun-java6-jdk

Afterwards make it available system wide:

update-java-alternatives -v -s java-6-sun

The screen output should be something like the following.

update-alternatives: error: no alternatives for xulrunner-1.9-javaplugin.so.

Note. Do not worry about error messages as long as the main "java" link is ok.

Check the alternative by typing as follows:

update-java-alternatives -l

You should get the following

java-6-sun 63 /usr/lib/jvm/java-6-sun

Step 3.2: Install Java Ant Compiler

Type as follows:

apt-get install ant ant-optional
