sending email from JSP page "Can not find host" or "auth fail" failed
I have been trying to write a piece of JSP code to general an email then send it to user. Unfortunately, I failed. I am stuck in here now.
Actuallyl, I have searched from Google and got some code about this functionality.
The first one is very similar to the code in the page [url]http://forum.java.sun.com/thread.jspa?threadID=760048&tstart=240[/url]
Because I use my private mailbox to test, I think there should be an authenticating process. I found such code in page [url]http://forum.java.sun.com/thread.jspa?threadID=709126[/url]
I did a little change. The most significant is I changed the "PopupAuthentication" to "PasswordAuthentication". But it does not work. The page is always in endless loading state. I don't know what happened. Because I am not very familiar with Java MAIL. If anybody can help, I will be very appreciate. Thanks
String host ="smtp.ihug.co.nz";
String from ="brabra@ihug.co.nz";
String to="bra@slingshot.co.nz";
String username="bra";
String password="bra";
// Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", host);
props.put("mail.smtp.auth","true");
props.put("mail.smtp.username", username);
props.put("mail.smtp.password", password);
// Setup authentication, get session
Authenticator auth =new PasswordAuthentication(username, password);;
// Get session
Session msession = Session.getDefaultInstance(props, auth);
// Define message
MimeMessage message =new MimeMessage(msession);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
message.setSubject("Your account is created");
message.setText("test");
Transport transport = msession.getTransport("smtp");
transport.connect(host,username,password);
transport.sendMessage(message,message.getAllRecipients());
transport.close();

Your first step should be to write a small stand-alone program (not a JSP or servlet) that helps you learn how to send e-mail from Java. Along with that you should read the JavaMail FAQ:
http://java.sun.com/products/javamail/FAQ.html
It is extremely likely to mention your problem, whatever it is.
try replacing the following line
Authenticator auth = new PasswordAuthentication(username, password);;
with
Authenticator auth = new Authenticator(){
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("username","password");
}
};
Thanks Clap's information. It is very useful. I am studying those questions.
And I have replaced the wrong code following Raee's suggestion. But there are some exceptions:
type Exception report

description The server encountered an internal error () that prevented it from fulfilling this request.

===========
Any suggestion. Does the code find the host. or the host simply refuses the host? what's happened?

But have decided to ignore them?Sorry, I am not sure your answer? Do you have any suggestion regarding this topic? I know little about Java Mail. Thanks
I tried to run the JSP page again. Same code as last time. This time the exception is:
type Exception report

very strange. This time it shows that connection to host failed. Godish! Who could help. Thanks.

What I mean't was that you have decided to ignore the advice given by DrClap and to ignore the content of the reference he gave.
I work with Java Mail and find it very easy BUT I don't try to embed it directly in a JSP page. I create a class that can be used in a JSP page (but normaly used in a servlet) but can be tested outside of the JSP.
Sabre150, thanks for your notice. I think I'd better read those reference completely before I ask quesiton. :-). If you don't mind, could you please post your code here. I could study your code. Heap of thanks.
> If you don't mind, could you please post your code> here. I could study your code. Heap of thanks.My code is pretty much straight from the examples given in the Javamail distribution but using the authentication approach given in reply 2 .
Oh. Thanks. I should study more carefully. I am wondering about port issue in this thread: http://forum.java.sun.com/thread.jspa?threadID=666312&tstart=0 There is a guy saying port25 is blocked by mail server provider. If blocked, how we use email agent to send email?
