javax.mail.SendFailedException: Sending failed;
nested exception is:
class javax.mail.MessagingException: 553 You are not authorized to send mail, authentication is required

身份验证失败，你的设置发送人的账号、密码有问题，还有你的代码怎么写在JSP上面哦？？不会建个Class？那么乱。。。

贴一段我写的JavaMail的Demo：
[code="java"]
package com._100fly.javamail;

import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.Message.RecipientType;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class SencMail {

/**
 * @param args
 * @throws MessagingException 
 * @throws AddressException 
 * @throws MessagingException 
 */
public static void main(String[] args) throws AddressException, MessagingException {
    // TODO Auto-generated method stub
    Properties props = new Properties();

    //两个属性必须配置

    //连哪种服务器
    props.setProperty("mail.transport.protocol", "smtp");
    //设置需要验证(给提供用户名、密码)
    props.setProperty("mail.smtp.auth", "true");
    props.setProperty("mail.host", "smtp.gmail.com");
    Session session = Session.getInstance(props,

            //返回验证信息的内部类
            new Authenticator()
            {

                protected PasswordAuthentication getPasswordAuthentication()
                {

                    return new PasswordAuthentication("[e-mail]","zeng@4717");
                }
            }

    );

    session.setDebug(true);

    Message msg = new MimeMessage(session);
    try {
        msg.setFrom(new InternetAddress("[e-mail]"));
        msg.setSubject("中文主题");
        msg.setRecipients(RecipientType.TO, InternetAddress.parse("[e-mail],[e-mail]"));
        msg.setContent("<span style='color:red'>我是以HTML代码解析出来的</span>", "text/html;charset=gbk");

        //没有指定收件人 会在msg里面去找
        Transport.send(msg);
    } catch (AddressException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (MessagingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

}
