我正在尝试将文件sqljdbc_auth.dll添加到项目库中.我将包含dll的文件夹添加为外部类文件夹.

在这里,我基本上尝试使用Microsoft提供的SQL驱动程序连接到我的SQL SERVER 2008数据库.

我的代码是

private static void Connect(){

try

{

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

String connectionUrl = "jdbc:hostname:1433;databaseName=dbname;"

+ "user=username;password=password";

java.sql.Connection con = DriverManager.getConnection(connectionUrl);

}

catch(ClassNotFoundException e)

{

e.printStackTrace();

}

catch(SQLException e2)

{

e2.printStackTrace();

}

}`

我收到以下错误
