Java Mail, sending multiple attachments not working

Question

I looked at many entries on the internet without having luck.

Here is my code:

import java.io.IOException;
import java.util.Properties;

import javax         


        

Answer 1

Just change the gmailUsername and gmailPass with actual gmail credentials. And also change the to and from address with your desired one. Here we have used Gmail SSL smtp port for sending mail. You can change it with your own mailing server details.

import java.util.*;

import javax.mail.*;
