SQL: com.microsoft.sqlserver.jdbc.SQLServerDriver not found error

Question

I am trying to connect to MySQL Server 2008 database from Java and I'm having the same problem from this thread.

String userName = "xxxx";
String password = "xxxx";
String url = "jdbc:sqlserver:xxx.xxx.xxx.xxx;databaseName=asdfzxcvqwer;integratedSecurity=true";
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
connection = DriverManager.getConnection(url, userName, password);

I also keep getting a ClassNotFoundException Whenever I try to load the driver from Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

I have also made sure that the necessary jdbc and jtds drivers are added to the library and CLASSPATH is set as well. I'm honestly not sure what went wrong here. 

Answer 1

You are looking at sqljdbc4.2 version like:

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

but, for sqljdbc4 version statement should be: 

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

I think if you change your first version to write the correct Class.forName , your application will be running.
