代码是：
import java.sql.*;
public class TestDB {
public static void main(String[] args)
{
String driverName = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
String dbURL = "jdbc:microsoft:sqlserver://localhost:1433; DatabaseName=jspdv";
String userName = "sa";
String userPwd = "19841015";
Connection dbConn ;
try {
Class.forName(driverName);
dbConn = DriverManager.getConnection(dbURL, userName, userPwd);
System.out.println("Connection Successful!");
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
报告有错误是：
