Hi All,

I am a newbie in the world of IntelliJ Idea plugin creation. I have tried to create a simple plugin from the examples provided. When I try to run this plugin, I get the following error.
Wrong JDK type for plugin module 'PluginName'.

I am using Intelli J Idea 5.0.
Project JDK JDK 1.6.

Please suggest.

THanks
Arnab
