QuickTip: Eclipse on Ubuntu : java.lang.ClassNotFoundException: org.eclipse.core.runtime.Plugin

This problem occurs if you do not have the JRE from Sun, but you are using the JRE from GNU. To get the JRE from Sun execute the following command

$sudo apt-get install sun-java5-jre

now you should get the JRE installed in the directory /usr/lib/jvm

if you hit $ java -version now you should see something like this

java version “1.5.0_13″
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05)
Java HotSpot(TM) Server VM (build 1.5.0_13-b05, mixed mode)

Now your Eclipse Europa should work without complaining.

Dual Boot Pre-Installed XP with Ubuntu Gutsy Gibbon

Last evening I installed Ubuntu Gutsy Gibbon (7.10) on my Dell Laptop which was pre-installed with Windows XP and it worked like a charm.

Though this is not the first time that I am installing Ubuntu for a dual boot environment however every time I tend to get a bit jittery on what would work and what would not.

Any way these are the steps that I followed which worked for me.
