把错误贴出来

我用smtp.163.com老是出javax.mail.AuthenticationFailedException.
自己用transport.isConnect()判断连接上了,就是发生这个异常,我也重写了认证类了,代码如下:
Session session = Session.getDefaultInstance(props,new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
PasswordAuthentication pa = new PasswordAuthentication( "lean1252 ", "lean433957 ");
if(pa == null) {
System.out.println( "auth failed... ");
}
return pa;
}
});
可它为什么问题提示认证失败了呢?
把smtp.gmail.com就能发送,不知道是什么原因
------解决方案--------------------
PasswordAuthentication pa = new PasswordAuthentication
