Send mail

[xxmp]

Hello
I want to sent mail and i am using this code

public boolean sendEmail(String from, String to, String subject, String themessage){
        boolean success=false;
        // Assuming you are sending email from localhost
        String host = "localhost";

        // 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);

        System.err.println("Gone thereee");
        try{
           // Create a default MimeMessage object.
           MimeMessage message = new MimeMessage(mailSession);
           System.err.println("From: "+from);
           // Set From: header field of the header.
           message.setFrom(new InternetAddress(from));
           System.err.println("Message from: "+message.getSender());
           // Set Subject: header field
           message.setSubject(subject);
           // Now set the actual message
           message.setText(themessage);
           System.err.println("To: "+to);
           // Set To: header field of the header.
           message.addRecipient(Message.RecipientType.TO, 
                      new InternetAddress(to));
           System.err.println("Message sender: "+message.getSender());
           //Send message
           Transport.send(message);
           success=true;;
        }catch (MessagingException mex) {
           //mex.printStackTrace();
            System.err.println("Problem in sending: "+mex.getMessage());
        }
        return success;
}

But when i try to send the mail i have this error

From: [e-mail]
Message from: null
To: [e-mail]
Message sender: null
Problem in sending: Invalid Addresses

Why the message from and message sender are null? They should not have value?
Thank you very much

Did you configure this properly:

properties.setProperty("mail.smtp.host", host);

If you are going to send email from localhost meaning on your own computer then you need to configure it correctly on your SMTP setting.

[jalpesh_007]

instead of using setproperties() method you can use put method also.
also configure your smtp host.

or use following

properties.put("mail.smtps.host","smtp.gmail.com");
properties.put("mail.smtps.auth","true");
