JavaMail问题

被时间遗忘的猴子 2009-09-03 03:51:33

我是最近才接触的JavaMail，我在JSP2.0技术手册中找了这个例子，想运行一下，可是却出现如下问题，请好心的高手帮忙看看谢谢！代码如下：

<%@ page language="java" contentType="text/html; charset=UTF-8"

	pageEncoding="UTF-8"%>

<%@ page import="javax.mail.*"%>

<%@ page import="javax.mail.internet.*"%>

<%@ page import="javax.activation.*"%>

<%@ page import="java.util.*"%>

<%@ page import="java.io.*"%>





<%

	InternetAddress[] address = null;

	request.setCharacterEncoding("UTF-8");



	String mailServer = "smtp.sina.com";

	String from = request.getParameter("from");

	String to = request.getParameter("to");

	String subject = request.getParameter("subject");

	String messageText = request.getParameter("message");



	try {

		//设定所要用的Mail服务器和所使用的传输协议

		Properties props = System.getProperties();

		props.put("mail.host", mailServer);

		props.put("mail.transport.protocol", "smtp");



		//产生新的Session服务

		Session mailSession = Session.getDefaultInstance(props, null);

		Message msg = new MimeMessage(mailSession);



		//设定传送邮件的发信人

		msg.setFrom(new InternetAddress(from));



		//设定传送邮件至收信人的信箱

		address = InternetAddress.parse(to, false);

		msg.setRecipients(Message.RecipientType.TO, address);



		//设定信中主题

		msg.setSubject(subject);



		//设定送信的时间

		msg.setSentDate(new Date());



		//设定传送信得MIME Type

		msg.setText(messageText);

	//	msg.saveChanges();



		//送信

		Transport.send(msg);



		out.println("邮件已顺利传送");



	} catch (MessagingException mex) {

		mex.printStackTrace();

	}
