Not sure what's wrong with the code, but you will definitely need to add authentication code (i.e., a password handler). No remote email server will let you connect these days without that.

i am using netbeans 6.1 activation.jar , mail.jar
i have tried another code using jauthencticate

package com.esd.Login;

import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
import javax.servlet.http.HttpServletRequest;

public class sendMail1{

public void send(HttpServletRequest req)
{
try
{
String host = "smtp.mail.com";
String from = "[e-mail]";
String to = "[e-mail]";
System.out.println("Host ="+host);
Properties props = System.getProperties();
props.put("mail.smtp.host", host);
props.put("mail.smtp.auth", "true");
JAuthenticate pAuth = new JAuthenticate("[e-mail]", "mypwd");
Session session = Session.getInstance(props, pAuth);
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
message.setSubject(" Multiple Attachments ");
MimeBodyPart messageBodyPart = new MimeBodyPart();
String mssg="Multiple Attachments Test Mail";
messageBodyPart.setText(mssg);
System.out.println(" Before senidng message to mail");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
Transport.send( message );
System.out.println(" After senidng message to mail");

}
catch(Exception e)
{
e.printStackTrace();
}
}
}

[Adinath Shirsath]

How is this question related to JSF?

Hi
Add this line:
props.put("mail.smtp.port", "465");
Then it will work fine,if not then add authentication code.

My program is working fine .
Below is my code:


import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

public class sms2
{
String d_email = "[e-mail]",
d_password = "xxxxx",
d_host = "smtp.gmail.com",
d_port = "465",
m_to = "[e-mail]",
m_subject = "Testing",
m_text = "Hey, this is the testing email.";

public sms2()
{
Properties props = new Properties();
props.put("mail.smtp.user", d_email);
props.put("mail.smtp.host", d_host);
props.put("mail.smtp.port", d_port);
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.auth", "true");
//props.put("mail.smtp.debug", "true");
props.put("mail.smtp.socketFactory.port", d_port);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");

SecurityManager security = System.getSecurityManager();

try
{
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getInstance(props, auth);
//session.setDebug(true);

MimeMessage msg = new MimeMessage(session);
msg.setText(m_text);
msg.setSubject(m_subject);
msg.setFrom(new InternetAddress(d_email));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));
Transport.send(msg);
}
catch (Exception mex)
{
mex.printStackTrace();
}
}

public static void main(String[] args)
{
sms2 blah = new sms2();
}

private class SMTPAuthenticator extends javax.mail.Authenticator
{
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(d_email, d_password);
}
}
}

your code is not working.... got following exception

  javax.mail.MessagingException: Unknown SMTP host: smtp.gmail.com; 
nested exception is: 
java.net.UnknownHostException: smtp.gmail.com   

[Rob Spoor]

Then check your network settings, because I can certainly resolve (and reach) smtp.gmail.com.

[Kaustubh G Sharma]

Please provide me idea to check it...

I would first google for "debug network issues" and then take it from there.

[Kaustubh G Sharma]

ohk thanks jaikiran
