我有這樣的代碼：的Java連接到SQL Server
try
{
Class.forName("net.sourceforge.jtds.jdbc.Driver");
Connection conn = DriverManager.getConnection(
"jdbc:jtds:sqlserver://myMachine:1433/myDB;instance=sql2008;user=myUserName;password=myPassword;"
);
System.out.println("connected");
}
catch (Exception e)
{
e.printStackTrace();
}
這是例外，我得到：
Unable to get information from SQL Server: myMachine.

在SQL配置管理器中我已經設置TCP/IP，命名管道，共享內存並將VIA設置爲啓用。
我已驗證提供的用戶名和密碼是否正確。端口號也是正確的。
爲什麼我得到這個錯誤以及如何解決這個問題？
PS：我正在使用sql server 2008 express
數據庫是否在1433端口上運行？如果你進入命令行，如果你使用'ping myMachine'，你會得到什麼（它是否解析爲IP？也就是說，myMachine是否解析爲可以從運行測試的地方訪問的IP地址？如果你從命令行執行'netstat -an'，你會看到'myMachine：1433'的TCP或UDP條目嗎？也就是說，SqlServer綁定到該主機名和端口（而不是本地主機或127.0。 0.1）？如果確實在運行，你可以在哪裏找到它，你可以用SqlServer Config Manager連接那個用戶名和pwd嗎？ – 2011-04-03 16:55:43
如果我做了netstat -an，我沒有看到任何端口號爲1433的東西。當我ping我的機器我得到這個：'回覆從fe80 :: 807e：73b6：47fb：9348％11：time <1ms'。我可以使用配置管理器的用戶名登錄 – Martijn 2011-04-03 17:02:47
@Martjin，你從'ping myMachine '？ – 2011-04-03 17:24:16
