// One way of connecting to a database is through the JDBC driver manager
// using the method DriverManager.getConnection. This method uses a string
// containing a URL. The following is an example of using the JDBC driver
// manager to connect to Microsoft SQL Server 2000 while passing the user
// name and password:

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Connection conn = DriverManager.getConnection
("jdbc:microsoft:sqlserver://server1:1433;User=test;Password=secret");
