用javamail发邮件问题，

boat2002w 2003-08-21 03:00:40

javax.mail.SendFailedException: Sending failed; nested exception is: javax.mail.MessagingException: Unknown SMTP host: smtp.jspinsider.com; nested exception is: java.net.UnknownHostException: smtp.jspinsider.com
这是什么错误？我用了新浪和eyou都不行。

还有从网上抄了这么一段代码，为什么不报错，也收不到信？
<%@ page contentType="text/html; charset=gb2312" %>
<%@ page import="java.util.*,javax.mail.*,javax.mail.internet.*,javax.activation.*,javax.swing.*,java.awt.*"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>无标题文档</title>
</head>
<%//标题
String message_subject="title";
//正文
String message_body="邮件正文内容！";

//JavaMail Session对象
Session psession;
//JavaMail Message对象
Message mesg;
Properties props=new Properties();
props.put("mail.smtp.host","smtp.sina.com.cn");//这里必须正确填入你的smtp（我这里添的是新浪的smtp）

psession=Session.getDefaultInstance(props,null);
psession.setDebug(true);

try
{
//创建一个邮件
mesg=new MimeMessage(psession);
//FROM地址
mesg.setFrom(new InternetAddress("wuwei0199_cn@sina.com"));
//TO地址
InternetAddress toAddress=new InternetAddress("wuwei0199_cn@sina.com");
mesg.addRecipient(Message.RecipientType.TO,toAddress);
//标题
mesg.setSubject(message_subject);
//正文
mesg.setText(message_body);

Transport transport = psession.getTransport("smtp");
transport.connect("smtp.sina.com.cn", "wuwei0199_cn","******");//这里添一个你自己的邮件用户名和密码（假如为xxx.sina.com，密码为1234）
//最后发送邮件
transport.send(mesg);
}
catch(MessagingException ex)
{
while((ex=(MessagingException)ex.getNextException())!=null)
{
ex.printStackTrace();
}
}
%>
<body>

</body>

leojeff(★爱上你等于爱上一种艺术★) ：
请问在jsp 页面中应该如何引入这个bean？
我觉得就是认证的问题，在jsp中怎样加入认证？
谢谢各位

你帮我仔细写一下代码可以吗？按照你上面写的报了好多错误，小地方我还能改，有的错误我就看不出来了。比如
D:\tomcat\work\Standalone\localhost\_\test\test5_jsp.java:73: illegal start of expression
transport.connect("smtp.sina.com.cn");, "wuwei0199_cn","1******");//当然我把密码改了
还有你好多变量都没有定义

看异常信息,好像是不能找到主机哦!
先获得主机的IP地址吧!

试试下面的代码!
如果不行,报什么异常???
Properties props = System.getProperties();
props.put("mail.smtp.host", "smtp.sina.com.cn");
props.put("mail.smtp.auth","true");
Transport transport;

Session session = Session.getDefaultInstance(props, null);
session.setDebug(false);
Message msg = new MimeMessage(session);
InternetAddress toAddress=new InternetAddress("wuwei0199_cn@sina.com");
mesg.addRecipient(Message.RecipientType.TO,toAddress);
mesg.setFrom(new InternetAddress("wuwei0199_cn@sina.com"));
msg.setHeader("X-Mailer", mailer);
msg.setSentDate(new Date());
mesg.setSubject(message_subject);
mesg.setText(message_body);

transport = session.getTransport("smtp");
transport.connect("smtp.sina.com.cn");, "wuwei0199_cn","******");//
transport.sendMessage(msg,msg.getAllRecipients());
transport.close();
