Code for Java Learners to Read a email at the Gmail.

I wanted my Raspberry PI to read my Emails.  So i needed a Java program to to read the mails. Most of the Java programs  I found on net were not working due to SSL certificate errors. Finally here i came up with a code that's working amazingly..!! Atleast for now..!!

2. import com.sun.mail.util.MailSSLSocketFactory;
3. import java.security.GeneralSecurityException;
4. import java.util.Properties;
5. import java.util.logging.Level;
6. import java.util.logging.Logger;

8. import javax.mail.Folder;
9. import javax.mail.Message;
10. import javax.mail.Session;
11. import javax.mail.Store;
12. import javax.mail.internet.InternetAddress;
13. 
    
14. public class Downloader {
15. 
    
16.  public static void main(String[] args) {
17.   Downloader gmail = new Downloader();
18.      try {
19.          gmail.read();
20.      } catch (GeneralSecurityException ex) {
21.          Logger.getLogger(Downloader.class.getName()).log(Level.SEVERE, null, ex);
22.      }
23.  }
24. 
    
25.  public void read() throws GeneralSecurityException {
26.      MailSSLSocketFactory socketFactory= new MailSSLSocketFactory();
27. socketFactory.setTrustAllHosts(true);
28. 
    
29.   Properties propsSSL = new Properties();
30.   propsSSL.put("mail.smtp.host", "smtp.gmail.com");
31.   propsSSL.put("mail.smtp.socketFactory.port", "465");
32.   propsSSL.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
33.   propsSSL.put("mail.smtp.port", "465");
34.   propsSSL.put("mail.imaps.ssl.socketFactory", socketFactory);
35.   propsSSL.put("mail.smtps.auth", "true");
36.      propsSSL.put("mail.smtps.ssl.checkserveridentity", "false");
37.      propsSSL.put("mail.smtps.ssl.trust", "*");
38.   try {
39.    
40.    Session session = Session.getDefaultInstance(propsSSL, null);
41. 
    
42.    Store store = session.getStore("imaps");
43.    store.connect("smtp.gmail.com", "yourmail@gmail.com","password");
44. 
    
45.    Folder inbox = store.getFolder("inbox");
46.    inbox.open(Folder.READ_ONLY);
47.    int messageCount = inbox.getMessageCount();
48. 
    
49.    System.out.println("Total Messages:- " + messageCount);
50. 
    
51.    Message[] messages = inbox.getMessages();
52.    System.out.println("------------------------------");
53.    for (int i = 0; i < messageCount; i++) {
54.       System.out.println("Mail Subject:- " + messages[i].getSubject());   
55.       System.out.println("Time: "+messages[i].getSentDate());
56.       System.out.println("From: " +InternetAddress.toString(messages[i].getFrom())+"\n"); 
57.    }
58.    inbox.close(true);
59.    store.close();
60. 
    
61.   } catch (Exception e) {
62.    e.printStackTrace();
63.   }
64.  }
65. 
    
66. }
