javamail 发邮件出现错误，帮我看看，谢谢了！~~
摘要: javamail 发邮件出现错误，帮我看看，谢谢了！~~
1、我下载了sun的javamail，并将mail.jar 复制到了lib目录下，重启动了服务器。
2、我直接在jsp里发邮件，代码如下
<%@page contentType="text/html;charset=utf-8"%>
<%@ page import="javax.mail.*, javax.mail.internet.*,java.util.*"%>
<head>
</head>
<body>
<%
Properties props = new Properties();
Session sendMailSession;
Transport transport;
sendMailSession = Session.getInstance(props,null);
Message newMessage = new MimeMessage(sendMailSession);
newMessage.setFrom(new InternetAddress("test@test.com"));
newMessage.setRecipient(Message.RecipientType.TO, new InternetAddress("wxg_bj@yahoo.com.cn"));
newMessage.setSubject("subject");
newMessage.setSentDate(new Date());
newMessage.setText("text");
props.put("mail.smtp.host","smtp.126.com");//存储发送邮件服务器的信息
props.put("mail.smtp.auth","true");//同时通过验证
transport = sendMailSession.getTransport("smtp");
transport.send(newMessage);
%>
</body>
3、提示错误如下：
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.

你没有JavaBeans Activation Framework
到sun的站点去下载。
将 activation.jar 文件添加到 CLASSPATH
谢谢,确实和这个有关系。 我下再了activation.jar 放到了lib里，并在jsp里import
已经解决部分错误。但我发邮件还是有问题。
问题出在最后一行
transport.send(newMessage);
发送的时候。
是不是126.com需要smtp的用户验证，该怎么写呢？
已经搞定，谢谢
