java发送电子邮件代码

在网上闲逛，发现一段电子邮件的代码，http://www.iteye.com/topic/251720正好要用，Ctrl+C,Ctrl+V下来试验了一下，正好可用，不过在MyEclipse里面，需要加载J2EE1.4的jar不能加载JEE5的包，代码如下：
package com.fox.example;

import java.security.Security;
import java.util.Date;
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.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class GmailSender {

    /**
     * @param args
     * @throws MessagingException
     * @throws AddressException
     */
    public static void main(String[] args) throws AddressException, MessagingException {
         Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
         final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
         // Get a Properties object
         Properties props = System.getProperties();
         props.setProperty("mail.smtp.host", "smtp.gmail.com");
         props.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY);
         props.setProperty("mail.smtp.socketFactory.fallback", "false");
         props.setProperty("mail.smtp.port", "465");
         props.setProperty("mail.smtp.socketFactory.port", "465");
         props.put("mail.smtp.auth", "true");
         final String username = "用户名";
         final String password = "密码";
         Session session = Session.getDefaultInstance(props, new Authenticator(){
             protected PasswordAuthentication getPasswordAuthentication() {
                 return new PasswordAuthentication(username, password);
             }});

              // -- Create a new message --
         Message msg = new MimeMessage(session);

         // -- Set the FROM and TO fields --
         msg.setFrom(new InternetAddress(username + "@gmail.com"));
         msg.setRecipients(Message.RecipientType.TO, 
           InternetAddress.parse("[e-mail]",false));
         msg.setSubject("Hello");
         msg.setText("How are you");
         msg.setSentDate(new Date());
         Transport.send(msg);
         
         System.out.println("Message sent.");

    }

}
不过不知道这样的代码拿来做群发好不好
