these 2 links may get you started. both are using javax.mail

daniel shiffman's e-mail processing example
example code from daniel shiffman for checking a POP3 account and sending emails from processing via SMTP.

Send Mail With Attachment Using JavaMail

for the latter example you would need to save the frame as a file first and then attach the file from the saved path to your mail.

best,

Yeey. It works. I can now send image files over email.

Thanks again.

Ok. Here's the code. I took it right from http://www.shiffman.net. And just replaced the message with a multipart message.

Three files.

save_attachment.pde
Code:

// Daniel Shiffman		   
// http://www.shiffman.net	 

// Simple E-mail Checking	  
// This code requires the Java mail library
// smtp.jar, pop3.jar, mailapi.jar, imap.jar, activation.jar
// Download:// http://java.sun.com/products/javamail/

import javax.mail.*;
import javax.mail.internet.*;

void setup() {
  size(200,200);
  
  sendMail();
  println("Finished");
  noLoop();
}
 

Auth.pde
Code:

// Daniel Shiffman		   
// http://www.shiffman.net	 

// Simple Authenticator	    
// Careful, this is terribly unsecure!!

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

public class Auth extends Authenticator {

  public Auth() {
    super();
  }

  public PasswordAuthentication getPasswordAuthentication() {
    String username, password;
    username = "username@gmail.com";
    password = "password";
    System.out.println("authenticating. . ");
    return new PasswordAuthentication(username, password);
  }
}

 

MailStuff
Code:

// Daniel Shiffman		   
// http://www.shiffman.net	 

// Example functions that send mail (smtp)
// You can also do imap, but that's not included here

// A function to check a mail account


// A function to send mail
void sendMail() {
  // Create a session
  String host="smtp.gmail.com";
  Properties props=new Properties();

  // SMTP Session
  props.put("mail.transport.protocol", "smtp");
  props.put("mail.smtp.host", host);
  props.put("mail.smtp.port", "587");
  props.put("mail.smtp.auth", "true");
  // We need TTLS, which gmail requires
  props.put("mail.smtp.starttls.enable","true");

  // Create a session
  Session session = Session.getDefaultInstance(props, new Auth());

  try
  {
    MimeMessage msg=new MimeMessage(session);
    msg.setFrom(new InternetAddress("username@gmail.com", "Name"));
    msg.addRecipient(Message.RecipientType.TO,new InternetAddress("recipient@address.com"));
    msg.setSubject("Email with Processing");
    BodyPart messageBodyPart = new MimeBodyPart();
 // Fill the message
    messageBodyPart.setText("Email sent with Processing");
    Multipart multipart = new MimeMultipart();
    multipart.addBodyPart(messageBodyPart);
   // Part two is attachment
    messageBodyPart = new MimeBodyPart();
    DataSource source = new FileDataSource("c:\\image.jpg");
    messageBodyPart.setDataHandler(new DataHandler(source));
    messageBodyPart.setFileName("image.jpg");
    multipart.addBodyPart(messageBodyPart);
    msg.setContent(multipart);
    msg.setSentDate(new Date());
    Transport.send(msg);
    println("Mail sent!");
  }
  catch(Exception e)
  {
    e.printStackTrace();
  }

}
 

I haven't found a way to send the file with a relative path, without the "c:\" (by the way, you need double \ so you escape one of them).

I don't have the part where I save the file, but it's not hard just to save it to "c:\image.jpg" and send that one.

I used my gmail account with that port and everything went well, although I don't know if the account/password are sent in the clear or encrypted, so you might wanna check first.

This is in acapulco's last message. Look at "Part two is attachment" comment, code to attach an image is there.
