java.sql.SQLException：找不到適合netbeans的驅動程序

我的PC和Mac上有相同的項目（netbeans）。當我嘗試在我的Mac上打開它時，得到「找不到合適的驅動程序」。我在兩個版本上都使用相同的庫/項目。我正在閱讀，我需要在glassfish文件夾中手動添加連接器的庫文件？但我不知道在哪裏java.sql.SQLException：找不到適合netbeans的驅動程序

我得到以下錯誤：

您的項目lib是否需要jar？ – kosa 2012-03-08 17:39:39

是的，我添加它。但我已經閱讀了一些地方，它可能無法檢測到它運行時，我需要將它放在另一個文件夾而不是導入它。我不知道在哪裏？ – 2012-03-08 17:58:10

它將是服務器的ext文件夾 – kosa 2012-03-08 18:55:35

下面是一個簡單的代碼從SQLServer數據庫讀取。數據庫名稱是「database1」。表名是「table1」。它包含兩列「uname」和「pass」。不要忘記添加「sqljdbc4.jar」到您的項目。

public class NewClass { 

    public static void main(String[] args) { 

     Connection conn = null; 
     String dbName = "database1"; 
     String serverip="192.168.100.100"; 
     String serverport="1433"; 
     String url = "jdbc:sqlserver://"+serverip+"\\SQLEXPRESS:"+serverport+";databaseName="+dbName+""; 
     Statement stmt = null; 
     ResultSet result = null; 
     String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver"; 
     String databaseUserName = "admin"; 
     String databasePassword = "root"; 
     try { 
      Class.forName(driver).newInstance(); 
      conn = DriverManager.getConnection(url, databaseUserName, databasePassword); 
      stmt = conn.createStatement(); 
      result = null; 
      String pa,us; 
      result = stmt.executeQuery("select * from table1 "); 

      while (result.next()) { 
       us=result.getString("uname"); 
       pa = result.getString("pass");    
       System.out.println(us+" "+pa); 
      } 

      conn.close(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
}
