Bundle Configuration in B2c Electronic store

[selvakumar_5984]

Hi, I am trying to implement the Bundle feature in default OOTB electronic store. I have added following extensions.

 <extension name='configurablebundlecockpits' />
 <extension name='configurablebundlefacades' />
 <extension name='configurablebundleservices' /> 
 <extension name='configurablebundleaddon' />

But it throws error when do ant initialize. In configurablebundlefacades-spring.xml on BundleCommerceOrderEntryPopulator bean..Do I need to do any additional changes to implement bundles?
