Code Examples - the logic layer and service

Question

Hello,

I am looking for sample projects/ project templates. which show an N-Teir application (perferably in C# but do not mind Java). so far i have found the following:

1. S#arp Architecture - which i think is awesome
2. DotFactory Patterens in Action - I have the .Net 2.0 copy, exellent, but it only shows crud

do you know any samples which include some logic, not just CRUD? where if somthing is saved somthing else may happen (work flow)

if you have an example which is build on S#arp Architecture that would be grand.

also any example where it demos the UI being seperated from the Service layer. so the UI will interact with the service layer via WCF or Webservices.
