Hello, im trying to develop an applet that uses the javaMail library, but i havent been able to get it work. It works well when i run it as a desktop application but the problem comes when i export it as an applet and then try to execute the sending email modules, i just tried it with a simple example and figured out the problem was with that library.

Heres the example i used. (After pressing a key the applet wont work anymore)

import javax.mail.*;
import javax.mail.internet.*;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
import java.util.Properties;

void setup() {
 size(640, 480);
 background(0);
}

void draw() {
 if(mousePressed)
   background(random(255));
}

void keyPressed() {
 try {
   new SimpleMail().send();  
 }catch(Exception e){}
 
}


class SimpleMail {

   private static final String SMTP_HOST_NAME = "smtp.domain.com";
   private static final String SMTP_AUTH_USER = "myemail@mydomain.com";
   private static final String SMTP_AUTH_PWD  = "mypassword";

   public void send() throws Exception{
       Properties props = new Properties();
       props.put("mail.transport.protocol", "smtp");
       props.put("mail.smtp.host", SMTP_HOST_NAME);
       props.put("mail.smtp.auth", "true");
       props.put("mail.smtp.starttls.enable","true");

       Authenticator auth = new SMTPAuthenticator();
       Session mailSession = Session.getDefaultInstance(props, auth);
       Transport transport = mailSession.getTransport();

       MimeMessage message = new MimeMessage(mailSession);
       message.setSubject("Subject");
       message.setContent("content", "text/plain");
       message.setFrom(new InternetAddress("myemail@mydomain.com"));
       message.setRecipient(Message.RecipientType.TO,
            new InternetAddress("email@domain.com"));
       transport.connect();
       transport.sendMessage(message,
           message.getRecipients(Message.RecipientType.TO));
       transport.close();
   }
   
    private class SMTPAuthenticator extends javax.mail.Authenticator {
       public PasswordAuthentication getPasswordAuthentication() {
          String username = SMTP_AUTH_USER;
          String password = SMTP_AUTH_PWD;
          return new PasswordAuthentication(username, password);
       }
    }
}


hope u can help me. thx

hello philho, thanks for ur reply

I signed my applet but it stills doesnt work

thank you anyways

philho thx again.

Enabling the java console was usefull cause it showed me an exception here it is:

Exception in thread "Animation Thread" java.lang.NoClassDefFoundError: javax/mail/Authenticator

Why it says it doesnt find that class, doesnt the processing exporter do it for me? i mean including dependences etc? thank you


Edit: I solved that exception problem adding manualy the jar related to javaMail library into the html code, the applet doesnt crash anymore but it doesnt send emails also lol
