java.sql.SQLException：netbeansに適切なドライバが見つかりません

Question

私は自分のPCとMac（netbeans）で同じプロジェクトを持っています。私がMacでそれを開こうとすると「適切なドライバが見つかりません」と表示されます。私は両方で同じライブラリ/プロジェクトを使用しています。私はglassfishフォルダの中にコネクタのライブラリファイルを手動で追加する必要があることを読んでいましたか？

Answer 1

後は、SQLServerデータベースから読み取るための単純なコードは次のとおりです。しかし、私はどこ

私は次のエラーを取得する知りません。 データベース名は "database1"です。 テーブル名は「table1」です。 "uname"と "pass"の2つの列があります。 "sqljdbc4.jar"をプロジェクトに追加することを忘れないでください。

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(); 
     } 
    } 
}
