I am building a desktop application with netbean.

I am building a desktop application with netbean but i keep getting an error message “java.sql.SQLException: No suitable driver found for jdbc:microsoft:sqlserver://127.0.0.1:1433;databaseName=LPSRepository;
“. I have downloaded and added the the sqljdbc. jar file and has set my DNS but no luck yet. Any help on this would be welcome.
