ClassNotFoundException occurs in connectivity with MS SQL Server - jdbc

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);
Exception : java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver

You have to add sqljdbc42.jar jar file in WEB-INF-->lib. just copy this jar file and paste in lib folder and then run it.
