i'm trying to read a simple email file from a folder in my computer.
I find this code but, it's not working.

i didn't understand theses lines:
what should i write for mail.host?
what should i write for "mail.transport.protocol", "smtp"?

props.put("mail.host", "smtp.gmail.com");
props.put("mail.transport.protocol", "smtp");

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

public class ReadEmail {

   public static void main(String args[]) throws Exception{
       display(new File("C:\\temp\\message.eml"));


   public static void display(File emlFile) throws Exception{
        Properties props = System.getProperties();
        props.put("mail.host", "smtp.gmail.com");
        props.put("mail.transport.protocol", "smtp");

        Session mailSession = Session.getDefaultInstance(props, null);
        InputStream source = new FileInputStream(emlFile);
        MimeMessage message = new MimeMessage(mailSession, source);

        System.out.println("Subject : " + message.getSubject());
        System.out.println("From : " + message.getFrom()[0]);
        System.out.println("Body : " +  message.getContent());

Is there a simple way to just read an email file that i've already saved in a folder. I don't want to connect to my gmail.

Thank you

It might help to know exactly what "doesn't work" entails.

"Doesn't work" doesn't help.

Thank you very much, it's really interesting for me.
