Which jars to be used for KM in local DC?

I am using Local DC, but don't have NWDI. I am using local DC as I want to include it into GP.

In my WebDynpro DC I am using some functionality related to KM so I need to use these.

WPUMFactory

ResourceContext

RID

IResourceFactory

ICollection

IResource

etc..

How do I give the reference to the jars which will have these?

When I do used DC I don't get the required references.

Which are the references which I need to do in Used DC and how?

Is there any way as this is local DC and I don't have NWDI?

I am on EP7 SP 15

Thanks,

VD
