我有一个JSP代码。我试着通过那个发送一封smtp电子邮件。它在以下方面有一个错误：

传送。发送（信息）

有人能帮我吗

代码如下：

 <%@ page import="java.io.*,java.util.*,javax.mail.*, javax.mail.Service"%>
 <%@ page import="javax.mail.internet.*,javax.activation.*"%>
 <%@ page import="javax.servlet.http.*,javax.servlet.*" %>
 <%
 String result;
 // Recipient's email ID needs to be mentioned.
 String to = "email@gmx.com";

 // Sender's email ID needs to be mentioned
 String from = "email@gmx.com";

 // Assuming you are sending email from localhost
 String host = "mail.gmx.com";

 // Get system properties object
 Properties properties = System.getProperties();

 // Setup mail server
 properties.setProperty("mail.smtp.host", host);

 // Get the default Session object.
 Session mailSession = Session.getDefaultInstance(properties);


  // Create a default MimeMessage object.
  MimeMessage message = new MimeMessage(mailSession);
  // Set From: header field of the header.
  message.setFrom(new InternetAddress(from));
  // Set To: header field of the header.
  message.addRecipient(Message.RecipientType.TO,
                           new InternetAddress(to));
  // Set Subject: header field
  message.setSubject("This is the Subject Line!");
  // Now set the actual message
  message.setText("This is actual message");
  // Send message
  Transport.send(message);
  result = "Sent message successfully....";

这是一个相当低级的问题。不允许正在执行当前Java运行时环境的操作系统平台指定用户打开到给定主机的网络连接

这可能有许多可能的原因，具体取决于用户的权限、对它的高级控制程度、防火墙设置、使用的操作系统等等。至少，问题不在Java代码中（免责声明：我还没有读过它，整个异常本身已经是答案，所以Java代码中可能仍然存在一些不相关的错误）

我将介绍一些常见的原因，以便您了解应该在哪里寻找解决方案：

Web应用程序部署到第三方主机，该主机不允许您的Web应用程序连接除第三方主机之外的任何主机。解决方案：升级帐户，以便您可以使用主机自己的邮件服务器（或者您已经有了它而不需要升级），或者迁移到另一台主机
操作系统平台特定的非管理员用户帐户不允许进行任何网络连接。管理员帐户必须相应地更改用户的帐户设置
操作系统平台安装了防火墙，其配置过于严格。尝试完全禁用防火墙，然后重新测试以排除可疑，然后在必要时重新配置防火墙
