求助关于jdbc连接sql server的配置问题？

[yuyong81]

编写jdbc程序需要配置jdbc.drivers,jdbc.url,jdbc.username,jdbc.password ，我想请教大家一下，这个jdbc.username应该怎么指定啊，我不知道哪个才是我的jdbc.username啊？

[hui3zhihui]

最简单的就是sa

jdbc.username:sa
jdbc.password:

[yuyong81]

写成sa总是可以的吗？
我在sql server2000里建了一个ScienceManage数据库，然后建了一个database.properties文件，内容是
jdbc.drivers=com.microsoft.jdbc.sqlserver.SQLServerDriver
jdbc.url=jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=ScienceManage
jdbc.username=sa
jdbc.password=
然后运行TestDB.java文件，
import java.sql.*;
import java.io.*;
import java.util.*;

/**
This program tests that the database and the JDBC
driver are correctly configured.
*/
class TestDB
{
public static void main (String args[])
{
try
{
Connection conn = getConnection();
Statement stat = conn.createStatement();

stat.execute("CREATE TABLE Greetings (Name CHAR(20))");
stat.execute(
"INSERT INTO Greetings VALUES ('Hello, World!')");

ResultSet result
= stat.executeQuery("SELECT * FROM Greetings");
result.next();
System.out.println(result.getString(1));
result.close();

stat.execute("DROP TABLE Greetings");

stat.close();
conn.close();
}
catch (SQLException ex)
{
while (ex != null)
{
ex.printStackTrace();
ex = ex.getNextException();
}
}
catch (IOException ex)
{
ex.printStackTrace();
}
}

/**
Gets a connection from the properties specified
in the file database.properties
@return the database connection
*/
public static Connection getConnection()
throws SQLException, IOException
{
Properties props = new Properties();
FileInputStream in
= new FileInputStream("database.properties");
props.load(in);
in.close();

String drivers = props.getProperty("jdbc.drivers");
if (drivers != null)
System.setProperty("jdbc.drivers", drivers);
String url = props.getProperty("jdbc.url");
String username = props.getProperty("jdbc.username");
String password = props.getProperty("jdbc.password");

return
DriverManager.getConnection(url, username, password);
}
}

运行后为什么是
