Java in Ubuntu 11

To get java installed perform these:

• sudo add-apt-repository 'deb http://archive.canonical.com/ lucid partner'
• sudo apt-get update
• sudo apt-get install sun-java6-jdk sun-java6-jre sun-java6-plugin
• sudo update-java-alternatives -s java-6-sun

You can verify everything went smooth with:

• java -version
• ls -lahF /etc/alternatives/java

Note: I'm using the "Lucid" code name for the repository because it simply worked. You should find the tag for your version.
