Java Mail questions should really be asked in the "Other Java APIs" forum. You are much more likely to get a sensible answer there, so I've moved this thread for you.

Extract your jar files ie, activation.jar & mail.jar present in your jaf1.0.1 & javamail1.2 packages.
A javax folder will be created in your weblogic\classes folder. set your classpath to include the weblogic\classes folder
And for your info. Imap hostname means the name of your computer where your mailserver is present.Your mailserver should be supporting the imap protocol. Imap protocol is the protocol available for reading of messages

The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp . We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please log in with a new name which meets the requirements.

you can either use IMAP or POP to receive the mails. Eg.
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
import java.io.*;

public class POP3Client {
public static void main(String[] args) {

Properties props = new Properties();
// host name here is the POP or IMAP server.
String host = "";
//here u can use the username to access the Inbox
String username = "";
String password = "";
//provider can either be POP or IMAP
String provider = "pop3";
try {
// Connect to the POP3 server
Session session = Session.getDefaultInstance(props, null);
System.out.println("I am after Session creation");
Store store = session.getStore(provider);
System.out.println("I am after getting the Store");
store.connect(host, username, password);

// Open the folder
Folder inbox = store.getFolder("INBOX");
if (inbox == null) {
System.out.println("No INBOX");

// Get the messages from the server
Message[] messages = inbox.getMessages();
for (int i = 0; i < messages.length; i++) {
System.out.println("------------ Message " + (i+1)
+ " ------------");
// Close the connection
// but don't remove the messages from the server

catch (Exception e) {

public static void printMessage(Message m) throws Exception {
// Print the message header
Address[] from = m.getFrom();
if (from != null) {
for (int i = 0; i < from.length; i++) {
System.out.println("From: " + from[i]);

Address[] to = m.getRecipients(Message.RecipientType.TO);
if (to != null) {
for (int i = 0; i < to.length; i++) {
System.out.println("To: " + to[i]);

String subject = m.getSubject();
if (subject != null) {
System.out.println("Subject: " + subject);

Date d = m.getSentDate();
if (d != null) {
System.out.println("Date: " + d);
// Print a blank line to separate the header from the body
// Print the message body
Object content = m.getContent();
if (content instanceof String) {
else if (content instanceof InputStream) {
InputStream in = (InputStream) content;
int c;
while ((c = in.read()) != -1) System.out.write(c);
else {
System.out.println("Unrecognized Content Type");

I tried it by demo program given with java mail api as explained at http://developer.java.sun.com/developer/onlineTraining/JavaMail/exercises/MailSetup/help.html But unable to do so. It is giving the error of pop authentication. I am unable to understand where to give the password. Please help me out.
