使用javamail发送邮件时出错

这是我发送邮件的代码

package com.markEffy.aggregator.util;
import com.sun.mail.util.MailSSLSocketFactory;

import java.util.Properties;

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

 public class EmailAgent {

        private static final String SMTP_HOST_NAME = "smtp.zoho.com";
        private static final String SMTP_PORT = "465";
        private static final String emailFromAddress = "support@jiffie.in";
        private static final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
        private String emailMsgTxt;
        private String emailSubjectTxt;
        private String[] sendTo = {""};

        private int msgBodyType;

        public EmailAgent (String sendToAddr, int msgType) throws Exception {
            this.sendTo[0] = new String(sendToAddr);
            this.msgBodyType = msgType;
            }
        public EmailAgent (String sendToAddr, String emailMsgTxt, String emailSubjectTxt) throws Exception {
            this.sendTo[0] = new String(sendToAddr);
            this.emailMsgTxt = emailMsgTxt;
            this.emailSubjectTxt = emailSubjectTxt;
            }

        public EmailAgent(String[] recipients, int msgType) {
            // TODO Auto-generated constructor stub
            this.sendTo = new String[recipients.length];
            for(int i=0;i<recipients.length;i++){
                this.sendTo[i]=recipients[i];
            }
            this.msgBodyType=msgType;

        }

        public  void sendMail() throws Exception {
            //System.out.println("inside send mail");

            MailSSLSocketFactory sf = new MailSSLSocketFactory();

            //Check if valid arguments are passed
            if ((this.sendTo == null)) {
                System.out.println ("Invalid arguments!");
                return;
            }

            int msgType = this.msgBodyType; 
            new EmailAgent(sendTo, msgType).sendSSLMessage(sendTo, emailSubjectTxt, emailMsgTxt,
                    emailFromAddress, sf);
            System.out.println("Sucessfully Sent mail to All Users");
        }

        public void sendSSLMessage(String recipients[], String subject,
                String message, String from , MailSSLSocketFactory sf) throws MessagingException {
            boolean debug = true;
            Properties props = new Properties();
            props.put("mail.smtp.host", SMTP_HOST_NAME);
            props.put("mail.smtp.auth", "true");
            props.put("mail.debug", "true");
            props.put("mail.smtp.port", SMTP_PORT);
            props.put("mail.smtp.socketFactory.port", SMTP_PORT);
            props.put("mail.smtp.socketFactory.class", SSL_FACTORY);
            props.put("mail.smtp.socketFactory.fallback", "false");

            Session session = Session.getDefaultInstance(props,
                    new javax.mail.Authenticator() 
                     {
                         protected PasswordAuthentication                   

                      getPasswordAuthentication() {
                            return new   
                         PasswordAuthentication("support@jiffie.in", "support@1234$");
                        }
                    });

            session.setDebug(debug);

            Message msg = new MimeMessage(session);
            InternetAddress addressFrom = new InternetAddress(from);
            msg.setFrom(addressFrom);

            InternetAddress[] addressTo = new InternetAddress[recipients.length];
            for (int i = 0; i < recipients.length; i++) {
                addressTo[i] = new InternetAddress(recipients[i]);
            }
            msg.setRecipients(Message.RecipientType.TO, addressTo);

            // Setting the Subject and Content Type
            msg.setSubject(subject);
            msg.setContent(message, "text/plain");

            Transport.send(msg);
       }
}

我在tomcat的lib文件夹中添加了mail.jar和activation.jar。我将eclipse与Tomcat7、JRE7和Struts2一起使用。通过Java发送邮件时出现以下控制台错误：

因此，我刚刚在这里测试了您的代码，该代码与以下两个邮件发送Architcatscom.sun.mail:javax.mail:1.5.2和javax.mail:javax.mail-api:1.5.2保持邮件工件的API部分和实现部分同步。因此，或者将mailapi-1.5.2更改为mailapi-1.4.7，或者将javamail impl从1.4.7更新为1.5.2。
