怎么解决javax.mail中，smtp的认证问题，就是发送邮件的时候，如何进行验证

javax.mail中有个authenticator类，如何使用，他介绍说要创建子类，但是创机子类後如何返回到javax.mail.session类中进行初始化呢？？

好了，我已经解决了
public static void mysendMail(String host,String from,String to ,String subject ,String context)
throws RemoteException
{
java.util.Properties property=new java.util.Properties ();
property.put("mail.smtp.host",host);
property.put("mail.smtp.auth","true");
try
{
Authenticator auth = new SmtpAuth("zhouhaojie","lovewindy");
javax.mail.Session session = javax.mail.Session.getDefaultInstance(property,auth ) ;
// javax.mail.internet.InternetAddress fromadress = new javax.mail.internet.InternetAddress (from);
InternetAddress fromadress = new InternetAddress(from);
javax.mail.internet.InternetAddress toadress= new javax.mail.internet.InternetAddress (to);
javax.mail.internet.MimeMessage mymessage = new javax.mail.internet.MimeMessage (session);
mymessage.setFrom(fromadress);
mymessage.setRecipient(Message.RecipientType.TO ,toadress);
// mymessage.setRecipient(Message.RecipientType.CC,new InternetAddress("[e-mail]"));
mymessage.setSentDate(new java.util.Date());
mymessage.addHeader("zhj","test") ;
mymessage.setSubject(subject) ;
mymessage.setText(context) ;
Transport tt=session.getTransport("smtp");
// tt.connect(host,"zhouhaojie","lovewindy") ;
tt.send(mymessage) ;
// javax.mail.Transport.send(mymessage) ;

}
catch (MessagingException e)
{
throw new RemoteException("error"+e.getMessage() );
}catch (Exception e)
{
throw new RemoteException("err"+e.getMessage() );
}

}


其中的SmtpAuth继承之javax.mail.Authenticator
static class SmtpAuth extends javax.mail.Authenticator {
private String user;
private String password;
public SmtpAuth(String newuser,String userpassword)
{
user=newuser;
password=userpassword;
}
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication (user,password);
}

}

class Authenticator1 extends Authenticator{
public PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication("user","password");
}
}
....
Session smtpSession = Session.getInstance(props,new Authenticator1());
具体的情况自己可以改Authenticator1类
