JavaMail not retrieving messages (I know they're there!!)

As a test, from the same program I was able to send to the mailbox. However, this has not provided any useful insights, as I still am getting an empty message array when reading. I would be exceptionally grateful for any insights, as I have not fixed the problem.

Also, I have confirmed that I can the folder (the Folder object I create for reading), because the folder.exists() value returns "true". Here is the updated program with the writing test at the beginning and non-working reading part at the end:

import java.util.Properties;

import javax.mail.Session;

import javax.mail.Store;

import javax.mail.Folder;

import javax.mail.Message;

import javax.mail.Transport;

import javax.mail.internet.MimeMessage;

import javax.mail.internet.InternetAddress;

public class MailService {

static String host = "192.168.1.174";

static String username = "Tim.Clotworthy@trim.demoapps.com";

static String password = "$M0thii9";

static String from = "JavaMail";

static String to = "Tim.Clotworthy@trim.demoapps.com";

/**

* @param args

*/

public static void main(String[] args) {

// Get system properties

Properties props = System.getProperties();

// Setup mail server

props.put("mail.smtp.host", host);

// Get session

Session session = Session.getDefaultInstance(props, null);

// Define message

MimeMessage message = new MimeMessage(session);

try{

message.setFrom(new InternetAddress(from));

message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));

message.setSubject("Hello JavaMail");

message.setText("Welcome to JavaMail");

// Send message

Transport.send(message);

} catch(Exception e){

e.printStackTrace();

}

// Create empty properties

//Properties props = new Properties();

// Get session

//Session session = Session.getDefaultInstance(props, null);

try {

// Get the store

Store store = session.getStore("pop3");

store.connect(host, username, password);

String dfolder = store.getDefaultFolder().getFullName();

// Get folder

Folder folder = store.getFolder("INBOX");

//folder.open(Folder.READ_ONLY);

folder.open(Folder.READ_WRITE);

int count = folder.getMessageCount();

String fname = folder.getFullName();

String name = folder.getName();

// Get directory

Message Rmessage[] = folder.getMessages();

for (int i=0, n=Rmessage.length; i<n; i++) {

System.out.println(i + ": " +

Rmessage.getFrom()[0]

+ "\t" + Rmessage.getSubject());

}

// Close connection

folder.close(false);

store.close();

} catch(Exception e){e.printStackTrace();}

}
