发送mail bean的方法如下 ... 为什么我写一个简单的应用程序来调用就可以发送,而用JSP 来调用就出现javax.mail.NoSuchProviderException: smtp的错误..谢谢!
public void sendmail()
{
try{
//Set up the default parameters
Properties props = new Properties();
props.put("mail.transport.protocol","smtp");
props.put("mail.smtp.host","smtp.163.com");
props.put("mail.smtp.auth","true");
props.put("mail.smtp.port","25");
// Create the session and create a new mail message
Session mailSession = Session.getInstance(props,null);
Message msg = new MimeMessage(mailSession);
// Set the FROM, TO, DATE and SUBJECT fields
msg.setFrom(new InternetAddress("(Feng)davisye@163.com"));
msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse("davisye@163.com"));
msg.setSentDate(new Date());
msg.setSubject("test");
//Create the body of the mail
msg.setText("Feng----Java mail 发送成功!");
//Ask the Transport class to send our mail message
System.out.println("正在发送邮件....");
//Session mailSession = Session.getInstance(props,null);
Transport transport = mailSession.getTransport("smtp");
transport.connect((String)props.get("mail.smtp.host"),"zfye","1234");
transport.sendMessage(msg,msg.getRecipients(Message.RecipientType.TO));
//transport.send(mimeMsg);
System.out.println("发送邮件成功！");
transport.close();
//Transport.send(msg);
}catch(Exception e){ System.out.println(e); }
如果一个应用程序可以调用。那应该是你JSP调用时方式有问题。比如参数未写全。或者不用USEBEAN标记。直接用JAVA语言在JSP来调用呢？
可以说说出的是什么错吗？贴些出错信息来。
我收到别人给我的代码，说是能用的，可我用在 JSP 中老是说联系不上 smtp 服务器！真是恼人！
关注中！
smtp.163.com
要验证的吧
