我的PC和Mac（netbeans）上有相同的项目。当我尝试在我的Mac上打开它时，“找不到合适的驱动程序”。我在两者上使用相同的库/项目。我正在阅读我需要在glassfish文件夹中手动添加连接器的库文件？但我不知道在哪里
我收到以下错误：

以下是从SQLServer数据库中读取的简单代码。 数据库名称是“database1”。 表名是“table1”。 它包含两列“uname”和“pass”。 别忘了在项目中添加“sqljdbc4.jar”。
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();
}
}
}
