IM與上述IM剛開d以下錯誤工作幫助用JavaMail API

我已按照

http://java.sun.com/developer/onlineTraining/JavaMail/contents.html

的例子，我應該如何得到output..will上面的代碼...工作有什麼變化，需要作出..使用雷鳥smtp服務器

該錯誤指示有兩個可能的Authenticator類別在此處被引用 - 即錯誤說明爲java.net.Authenticator and javax.mail.Authenticator。

這是因爲你已經導入了java.net。*和javax.mail。*，編譯器不知道你需要哪個Authenticator。

通過明確進口

import javax.mail.Authenticator;

或資格認證者上線22

javax.mail.Authenticator authenticator = new javax.mail.Authenticator()

UPDATE

既然你有PROBL修復此ems發送郵件，首先檢查您的網絡管理員是否授予您連接到Gmail的smtpserver的權限。你是否支持代理？在消息sess.setDebug(true);

看看，看看你走多遠：

創建sess後，加入這一行的代碼。

嘗試在給定其他調試提示：http://java.sun.com/products/javamail/FAQ.html#debug

更新2

我試着運行你的代碼，它爲我工作，包括髮送電子郵件。我不得不這樣return new PasswordAuthentication("user", "pass");添加一行道具

props.put("mail.smtp.starttls.enable","true");

，當然還有，改變你的實際用戶名/密碼。和「[email protected]」到您的實際電子郵件ID。

我改變了代碼，這...這工作沒有錯誤，罰款...但發送郵件的心不是我檢查收件箱，但沒有郵件... !!什麼問題

javax.mail.Authenticator authenticator = new javax.mail.Authenticator() \t { protected javax.mail.PasswordAuthentication getPasswordAuthentication() \t \t { return new javax.mail.PasswordAuthentication("[email protected]", "pass"); } };
