Biztalk integration with Commerce server

I am working over the integration of Biztalk server 2006 with Commerce server 2007 beta. I am trying to integrate biztalk server with Commerce server through commerce server catalog adapter. But I am facing a lot of problems. Can you suggest me a working example that may lead me from scratch towards end while using commerce server adapter.

I am desperately in need of such example as I have searched out a lot over web but couldn’t find any working example in which commerce server adapter has been used
