First I'll admit I'm not 100% sure this is the right place for this
message.
Anyhow, what I'm trying to do is create a program that will send an email
to one source. Many of the examples I've found online are more complex,
allowing you to pass arguments for the to, from, and host. The simplest
one i found is this:
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
// Send a simple, single part, text/plain e-mail
public class TestEmail {
public static void main(String[] args) {
// SUBSTITUTE YOUR EMAIL ADDRESSES HERE!!!
String to = "vipan@vipan.com";
String from = "vipan@vipan.com";
// SUBSTITUTE YOUR ISP'S MAIL SERVER HERE!!!
String host = "smtp.yourisp.net";
// Create properties, get Session
Properties props = new Properties();
// If using static Transport.send(),
// need to specify which host to send it to
props.put("mail.smtp.host", host);
// To see what is going on behind the scene
props.put("mail.debug", "true");
Session session = Session.getInstance(props);
try {
// Instantiatee a message
Message msg = new MimeMessage(session);
//Set message attributes
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject("Test E-Mail through Java");
msg.setSentDate(new Date());
// Set message content
msg.setText("This is a test of sending a " +
"plain text e-mail through Java.\n" +
"Here is line 2.");
//Send the message
Transport.send(msg);
}
catch (MessagingException mex) {
// Prints all nested (chained) exceptions as well
mex.printStackTrace();
}
}
}//End of class
This code can be found at http://www.vipan.com/htdocs/javamail.html.
When I went to use this, i changed the to, from, and host variables to
match my data and when i test the code their are no errors and it seems
like the program runs fine but i never receive an email. I'm not sure if I
have to put my host at: props.put("mail.smtp.host", host); and i tried it
with the default data and with my host, but neither work.
If anyone has suggestions on what to do or an easy way to send emails
advice is greatly appreciated
Thanks In Advance,
James

Try asking at the Sun-Java newsgroups because this is a general mail-API
problem and has no relevance to eclipse.
