Java Mail 发送邮件的问题 ....

Question

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？

Answer 1

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！

try
         {
               SmtpClient client = new SmtpClient(mail.getHost());
               client.from(mail.getFrom());
               client.to(mail.getTo());
               PrintStream message = client.startMessage();
               message.println("To:" + mail.getTo());
               message.println("Subject:" + mail.getSubject());
               message.println();
               message.println();
               message.println(mail.getContext());
               message.println();
               client.closeServer();
            } catch (Exception e){
                 System.out.println(e.getLocalizedMessage());
                 return false;
            }
            return true;
