Check the path in the file and location where you have kept the jar file.
I feel the location is creating the issue, its very evident that the jar file is not been located by the connection.
Hope you had a bounce before testing.
The problem got solved ..
Actually the path was correct but the driver class name was wrong ..
Perhaps it tries to find the driver class with the specific name in specified .jar
I thought we are CREATING new thing ..
Thanks anyways for your help
