Exception in running a small plugin

Hi All,

I am new to this plugin development. Am using IDEA 6.0.
As per the live demo given in IntelliJ plugin section, I downloaded the plugin development package and extracted in my IntelliJ home dircetory. Tried writing a small action in tools menu. After doing this I created a new 'Run Configuration' for this plugin. When I try to run / debug it, Intellij is trying to open a new instance and I get the below mentioned exception.

Caused by: java.lang.ClassNotFoundException: com.intellij.openapi.samples.ActionsPlugin
at com.intellij.ide.plugins.cl.PluginClassLoader.loadClass(PluginClassLoader.java:3)

[   4156]  ERROR - ij.components.ComponentManager - Error while initializing component: com.intellij.openapi.samples.ActionsPlugin:com.intellij.openapi.samples.ActionsPlugin

1. Why is it trying to open the Sample projects?
2. Am I missing something in setting up a plugin project?
3. I checked for this 'ActionsPlugin' in 'openapi.jar' and found that in 'com.intellij.openapi' package, there is no 'samples' package available.

Can someone please help me in overcoming this small exception.
