Problem faced while integrating Cactus with WSAD 5.1

Hi,
     I  am trying to integrate Cactus with WSAD 5.1. I followed the steps mentioned in Sheldon's tutorial. But when I run my Cactus test case I get the following exception related to logger configuration failure on the client side.

Any pointer to the possible fix will be greatly appreciated.
Thanks in advance.
