problem with caf application

Hi

I am trying to implement an application from sdn

https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/

I created the corresponding caf project also.

I hav a Remote Exception and Runtime Exceptions while deploying caf application.The versions of my nwds and j2ee engine are 7.0.

A hard reference type "tc/conn/connector framework" was added to application-j2ee-engine.xml

regards

ms
