android soap調用異常

您好我必須開發android登錄mysql數據庫連接使用soap web服務。android soap調用異常

其成功的工作我（本地主機/ phpMyAdmin的）

Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/androidlogin","root","");

但它不會對我的開發工作現場（dev.www.com/phpmyadmin）

Connection con = DriverManager.getConnection("jdbc:mysql://dev.www.com:3306/login","mm2","mm5");

我已經使用上面的代碼意味着我得到以下error.please給我如何解決這個錯誤。

我得到以下錯誤：

java.sql.SQLException: Unable to connect to any hosts due to exception:  java.net.SocketException: java.net.ConnectException: Operation timed out

檢查您是否可以首先從命令行訪問您的mysql服務器：mysql --host = localhost --user = myname --password = mypass mydb – deefactorial

這不是一個代碼問題。這是你的環境中的東西，所以我不確定這裏有多少人能夠幫助你。這裏有幾個提示。異常消息是：

java.net.ConnectException: Operation timed out

這排除了幾件事情。如果你能夠訪問主機www.dev.com但是mysql沒有運行，你應該得到java.net.ConnectException: Connection refused。如果您錯誤輸入了地址（例如www.dev.comm），您將得到java.net.UnknownHostException: <host name>。

不幸的是你得到了超時錯誤。這意味着主機名已成功解析爲一個地址，但是當您嘗試連接到該地址時，您完全沒有從計算機獲得任何響應。這通常意味着兩種情況之一：

有人關掉電腦
有防火牆你和電腦和防火牆不允許端口的TCP連接之間開啓3306

我猜這是防火牆。祝你好運。希望這可以幫助。
