ClassNotFoundException occurs in connectivity with MS SQL Server

Question

I have MS SQL Server 2008 database on server pc and I am trying to connect with that database from my local machine. On my local machine I have MS SQL Server 2012 and I have connected 2008 server database in my local pc. I have also added external jar file sqljdbc42.jar. When I run my java web application I get a ClassNotFoundException.

code:

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

Connection con=DriverManager.getConnection(Provider.CONNECTION_URL,Provider.USERNAME,Provider.PASSWORD);
        System.out.println("Connection........."+con);
        Statement stmt=con.createStatement();
        System.out.println("Statement...");
        String sql="select User_name,Password from tblBTUserMaster";
        ResultSet rs=stmt.executeQuery(sql);
        rs.next();
         name1=rs.getString(4);
         password1=rs.getString(6);
