i think driver is loaded successfully but not connected to the database.


No it is not loaded at all because it is not found. Where did you put the driver ? You should put it in WEB-INF/lib

I think that the driver class is not correct (uppercases) :
Try with com.microsoft.jdbc.sqlserver.SQLServerDriver

Maybe you're using a wrong URL. Please post it using dummy connection parameters.

By the way, there is also JDBC forum where you can post that kind of questions:
https://coderanch.com/forums/f-3/JDBC

And maybe you should read the FAQ about JDBC connection issues:
