我想从jboss的servlet发送一封电子邮件。我在jboss mail-service.xml文件中进行了更改。这是我的servlet代码。

try {
Properties props = new Properties();
props.setProperty("mail.host", "smtp.gmail.com");

msg.setText(message);
msg.setSubject(subject);
msg.setFrom(new InternetAddress(from));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
Transport.send(msg);
} catch (AuthenticationFailedException ex) {
/*request.setAttribute("ErrorMessage", "Authentication failed");

dispatcher.forward(request, response);*/
System.out.println("Authentication failed");

dispatcher.forward(request, response);*/
System.out.println("Wrong Email Address");
} catch (MessagingException ex) {

dispatcher.forward(request, response);*/
System.out.println("asdsad"+ex.getMessage());
}
/*RequestDispatcher dispatcher = request.getRequestDispatcher(succ);
dispatcher.forward(request, response);*/
System.out.println("Success");
}
private class SMTPAuthenticator extends Authenticator {
private PasswordAuthentication authentication;
public SMTPAuthenticator(String login, String password) {
authentication = new PasswordAuthentication(login, password);
}
protected PasswordAuthentication getPasswordAuthentication() {
return authentication;
}
}
protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
protected void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
}
这是我的mail-service.xml文件。
mbean code="org.jboss.mail.MailService" name="jboss:service=Mail">
<attribute name="JNDIName">java:/Mail</attribute>
<attribute name="User">*****@gmail.com</attribute>

但是在运行时我得到以下异常和根本原因。

我哪里出错？
答案 0 :(得分：3)
mailservice.xml没有变化。在你的servlet的doPost方法中删除其他所有内容并粘贴它。我希望它适合你。
String host = "smtp.gmail.com";
String from = "user@gmail.com";
String pass = "*******";
Properties props = System.getProperties();
props.put("mail.smtp.starttls.enable", "true"); // added this line
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", pass);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
String[] to = {"usr@yahoo.in"}; // added this line
Session session = Session.getDefaultInstance(props, null);
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
InternetAddress[] toAddress = new InternetAddress[to.length];
// To get the array of addresses
for( int i=0; i < to.length; i++ ) { // changed from a while loop
toAddress[i] = new InternetAddress(to[i]);
}
System.out.println(Message.RecipientType.TO);
for( int i=0; i < toAddress.length; i++) { // changed from a while loop
message.addRecipient(Message.RecipientType.TO, toAddress[i]);
}
message.setSubject("sending in a group");
message.setText("Welcome to JavaMail");
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
