#1

呵呵，帮你up....

#2

获得要发的email地址
触发发送

#3

哈哈自已动手去找吧网上多的是

#4

^_^，我看了好多，但是还是没有弄好

#5

JAVAMAIL解压后，将路径加进CLASSPATH，还需要做啥准备，才可以调用它的方法吗

#6

很简单的,邮件列表我就做过了,字段就没,不过,你做过个触发不就行了,用javamail作,你先要去java.sun.com下载javamail和jaf包,解压,把和mail.jar
和activation.jar加到classpath中去,然后就是用javamail的api编程,看看javamail api的doc很简单的

HELP！现在是JAVA我可以搞定，但是JSP搞不定
它说我ATTRIBUTE NOT VALUE

<%@ page

　　 import=" javax.mail.*, javax.mail.internet.*, javax.activation.*,java.util.*"

　　 %>

　　<html>

　　<head>

　　<TITLE>JSP meets JavaMail, what a sweet combo.</TITLE>

　　</HEAD>

　　<BODY>

　　<%

　　 try{
     String host = "smtp.163.net";
     String from="rain_voice@163.net";
String to=request.getParameter("to");
String subject=request.getParameter("subject");
String text=request.getParameter("text");
     String username = "name";
     String password = "password";
　　 Properties props = new Properties();
     props.put("mail.smtp.host", host);
     props.put("mail.smtp.auth", "true");
            Session session = Session.getDefaultInstance(props);

                      session.setDebug(true);

            MimeMessage message = new MimeMessage(session);

　　 message.setFrom(new InternetAddress(from));

　　 message.setRecipient(Message.RecipientType.TO, new InternetAddress(to));

　　 message.setSubject(subject);

　　 message.setSentDate(new Date());

　　 message.setText(text);

     message.saveChanges();
     Transport transport = session.getTransport("smtp");
     transport.connect(host, username, password);
     transport.sendMessage(message, message.getAllRecipients());
     transport.close();

　　 %>

　　<P>Your mail has been sent.</P>

　　<%

　　 }

　　 catch(MessagingException m)

　　 {

　　 out.println(m.toString());

　　 }

　　%>

　　</BODY>

看看，错在那里

Java mail不如sun.net.smtp好用，你可以这样试试：

import sun.net.smtp.*;

  ...
  host="your host name";
  from="aaa@aaa.com";
  to=rs.getString("bbb@bbb.com");
  SmtpClient smtp=new SmtpClient(host);
  smtp.from(from);
  smtp.to(to);

  PrintStream msg=smtp.startMessage();
  msg.println("From: "+from);
  msg.println("To: "+to);
  msg.println();
  msg.println("this is a mail test.");
  msg.close();

  smtp.closeServer();
  ...

可以了嘛

weidegong(weidegong:

在你产这个程序中smtp sever设为smtp.263.net

可是form只能是XXX＠263.net的形式时，邮件才能发送成功，这是怎么回事？

怎样才能解决这问题？

谢谢！！

#16

To ajzhn(梦醉生):
这个很简单了。String host = "smtp.263.net";把这句改一下，你用哪个Email发送邮件，就用哪个的smtp服务器，比如，如果你使用新浪的邮箱来发送，那么String host = "smtp.sina.com.cn";

......weidegong慢慢地转过身去，自言自语道：不会吧，这位老兄居然连邮件发送的常识都不懂，还想发邮件？呵呵呵。。。

司仪：食神首先品尝的就是大龙凤酒楼的总厨，戴龙师傅的“皇帝炒饭”。

食神：好！居然能够把米放在基围虾里面来蒸熟，再用整只*鲍鱼榨汁，加上*“官燕”来炒，表面上看起来呢是平凡无奇的炒饭，其实是精雕细琢，高深莫测，不愧是有“炒王”的称号。

（戴师傅得意的笑）

可惜，水分太多，饭粒太软影响口感，没想到你连炒饭最基本的常识都不懂－－要用隔夜饭来炒啊，炒王。零分！

戴师傅：啊？！
