v3.0.2 problem with MSSQL

I am not able to run registry v3.0.2 with MSSQL Server. I have modified reigistry.xml and user-mgt.xml to point to MSSQL and I have placed the sqljdbc.1.2.jar in the wso2greg-3.0.2\repository\components\lib directory. I can see that an OSGI bundle for the driver gets created and placed in the wso2greg-3.0.2\repository\components\dropins directory (sqljdbc.1.2_1.0.0.jar), but that does not seem to be enough. I have tried to place driver in the wso2greg-3.0.2\repository\components\extensions as well, but that behaves the same way. Below is the error I get. Does anyone have an idea what is going wrong and how to get around this problem?
