Bishal,
you have twice sqljdbc.jar
C:\Program Files\Microsoft SQL Server\Microsoft SQL Server JDBC Driver 2.0\sqljdbc_2.0\enu\
sqljdbc.jar/sqljdbc.jar You need to point to (don't unzip sqljdbc.jar):
C:\Program Files\Microsoft SQL Server\Microsoft SQL Server JDBC Driver 2.0\sqljdbc_2.0\enu\sqljdbc.jar
JDBC Driver path point to your driver (jar or zip file(s))
The driver native path point to your native libraries (dll in windows so in *nix)
The native libraries are needed when you use T2 driver (local, DB in same machine) if you use T4 (DB in remote machine) you don't need native libraries.
Normally in SQL Server sqljdbc.jar is T2 driver so you need to read how to install the driver usually at this level
C:\Program Files\Microsoft SQL Server\Microsoft SQL Server JDBC Driver 2.0\sqljdbc_2.0\enu\
You will have a directory with instructions on how to install the driver.
I suggest to use the next driver:
Microsoft SQL Server JDBC Driver 3.0
