Using Sun's Java (jdk) with Eclipse on Ubuntu

Let’s face it, if you’re reading this article, you know what Eclipse is, and what you’re trying to do.  Follow the jump for how to do it. First, install Sun’s Java 6 jdk, and Eclipse: sudo apt-get install eclipse sun-java6-jdk

Now, set up the newly installed jdk as the system default: sudo update-java-alternatives -s java-6-sun

Next, set your default jvm: sudo vim /etc/jvm

and add this line at the top of the file: /usr/lib/jvm/java-6-sun

Now, that should do the trick, but the Eclipse packaged with Ubuntu is packaged to prefer GCJ.  Let’s fix that: sudo vim /etc/eclipse/java_home

and again add this line at the top of the file: /usr/lib/jvm/java-6-sun

Finally, while you’re at it, bump up your Xms here: sudo vim /usr/lib/eclipse/eclipse.ini
