在java版经常看到有人问如何用javamail发送邮件？如何接收邮件？如何访问多个文件夹等。问题零散，而历史的回复早已经淹没在问题的海洋之中。
本人之前所做过一个java项目，其中包含有WebMail功能，当初为用java实现而对javamail摸索了一段时间，总算有点收获。看到论坛中的经常有此方面的问题，因此把我的一些经验帖出来，希望对大家有些帮助。
此篇仅介绍用javamail实现发送邮件功能，其中涉及smtp认证，邮件附件发送，及HTML内容邮件等。
其它有关多邮箱的实现，接收POP3邮件及IMAP等内容，将在后续文章中介绍。
如下程序需要：javamail，JAF包，j2ee.jar包含了上述两个包，建议大家安装J2SDKEE或直接拷贝j2ee.jar，将其添加到jbuilder的library中，或系统ClassPath中

我是按照weblogic公司的帮助文档做的。不知还要配置什么？
1. 通过console方式创建一个MailSession.
2. 在Configuration栏中输入以下参数：
Name: MyMailSession
JNDIName: MyMailSession
Properties
mail.smtp.host=winqiu
3. 然后在Targets栏中将mailsession加入你的Target Servers.
4. 这样你的mailsession就创建成功了.
5. 在程序中调用的方法如下：
import java.util.*;
import javax.activation.*;
import javax.mail.Session;
import javax.mail.*;
import javax.mail.internet.*;
import javax.naming.*;
public class SendMail {
Context ic = null;
public SendMail() {
}
public void send() {
//使用JNDI查询Mail Session，
try
{
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL, "t3://winqiu:7001");
ic = new InitialContext(ht);
Session session = (Session) ic.lookup("myMailSession");
//设置属性，然后创建Session实例
Properties props = new Properties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", "winqiu");
InternetAddress emailAddress = new InternetAddress(
"win_qiu@yahoo.com.cn");
props.put("mail.from", emailAddress);
Session session2 =session.getInstance(props);
//创建消息
Message msg = new MimeMessage(session2);
msg.setFrom();
String to = "win_qiu@hotmail.com.cn";
msg.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to, false));
String subject = "hello";
msg.setSubject(subject);
msg.setSentDate(new Date());
// 将消息内容存放到MimeBodyPart对象中，然后把MimeBodyPart对象
//存入Multipart对象中，最后，把代表附件的Multipart对象加入待
//发送的消息中
MimeBodyPart mbp = new MimeBodyPart();
String messageTxt = "first mail ";
mbp.setText(messageTxt);
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp);
msg.setContent(mp);
msg.saveChanges();
//发送消息
Transport.send(msg);
}
catch (NamingException e) {
e.printStackTrace();
}
catch (MessagingException e) {
e.printStackTrace();
}
}
public static void main(String args[])
{
SendMail sendMail=new SendMail();
sendMail.send();
System.out.println("send ok");
}
}
但是我的发送邮件时候就出现这样的异常：
