Problem in retrieving email using java mail api

hi,
In my project,i am retrieving mails from a particular email id.
I am able to retrieve the latest mails and save it in a folder in my system.
The problem is whenever i run the program eventhough the most recently received mail in inbox is retrieved and saved,again it is retrieving the same one and saving it in the same folder(not repeating).
I tried to check the newmessages in the inbox using the folder.hasNewMessage() method in java mail api,but the method is returning false only regardless new mail is there in inbox or not.
I want to read the unread messages only.Dont want to retrieve the already read mails.
I got the mail retrieving code from the below site.(sorry not posting the code because it is so long and having 4 classes)
http://www.builderau.com.au/program/java/soa/Getting_the_mail_in_receiving_in_JavaMail/0,39024620,39228060,00.htm
Can anyone tell me how to read unread mails in the inbox?
Thanks a lot

hi parvathi
i think your mail program is receving mails using imap
the imap is only receve the mail from server but the pop is deleting the mails after receving
use the following sample code
package com.sfrc.mail.pop;
import javax.mail.*;
import javax.mail.internet.*;
import com.sun.mail.handlers.message_rfc822;
import java.util.*;
import java.io.*;
* Owner: SFRC IT Solutions Pvt Ltd
* Author:Arunkumar Subramaniam
* Date :12-06-2006
* File Name: AttachRecive.java
public class AttachRecive
public static void main(String args[])
try
String popServer="192.168.1.1";
String popUser="pl";
String popPassword="password";
// Create empty properties
Properties props = new Properties();
// Get session
Session session = Session.getDefaultInstance(props, null);
// Get the store
Store store = session.getStore("pop3");
store.connect(popServer, popUser, popPassword);
// Get folder
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
// Get directory
Message message =folder.getMessages();
Multipart mp = (Multipart)message.getContent();
for (int i=0, n=mp.getCount(); i<n; i++) {
Part part = mp.getBodyPart(i);
String disposition = part.getDisposition();
// Close connection
folder.close(false);
store.close();
catch (Exception ex)
System.out.println("Usage: "
+" popServer popUser popPassword");
System.exit(0);

  • Problem in sending messages using java mail api

    Hi All,
    I have a problem in sending messages via java mail api.
    MimeMessage message = new MimeMessage(session);
    String bodyContent = "ñSunJava";
    message.setText (bodyContent,"utf-8");using the above code its not possible for me to send the attachment. if i am using the below code means special characters like ñ gets removed or changed into some other characters.
    MimeBodyPart messagePart = new MimeBodyPart();
                messagePart.setText(bodyText);
                // Set the email attachment file
                MimeBodyPart attachmentPart = new MimeBodyPart();
                FileDataSource fileDataSource = new FileDataSource("C:/sunjava.txt") {
                    public String getContentType() {
                        return "application/octet-stream";
                attachmentPart.setDataHandler(new DataHandler(fileDataSource));
                attachmentPart.setFileName(filename);
                Multipart multipart = new MimeMultipart();
                multipart.addBodyPart(messagePart);
                multipart.addBodyPart(attachmentPart);
                message.setContent(multipart);
                Transport.send(message);is there any way to send the file attachment with the body message without using MultiPart java class.

    Taken pretty much straight out of the Javamail examples the following works for me (mail read using Thunderbird)        // Define message
            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress(from));
            // Set the 'to' address
            for (int i = 0; i < to.length; i++)
                message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
    // Set the 'cc' address
    for (int i = 0; i < cc.length; i++)
    message.addRecipient(Message.RecipientType.CC, new InternetAddress(cc[i]));
    // Set the 'bcc' address
    for (int i = 0; i < bcc.length; i++)
    message.addRecipient(Message.RecipientType.BCC, new InternetAddress(bcc[i]));
    message.setSubject("JavaMail With Attachment");
    // Create the message part
    BodyPart messageBodyPart = new MimeBodyPart();
    // Fill the message
    messageBodyPart.setText("Here's the file ñSunJava");
    // Create a Multipart
    Multipart multipart = new MimeMultipart();
    // Add part one
    multipart.addBodyPart(messageBodyPart);
    // Part two is attachment
    for (int count = 0; count < 5; count++)
    String filename = "hello" + count + ".txt";
    String fileContent = " ñSunJava - Now is the time for all good men to come to the aid of the party " + count + " \n";
    // Create another body part
    BodyPart attachementBodyPart = new MimeBodyPart();
    // Get the attachment
    DataSource source = new StringDataSource(fileContent, filename);
    // Set the data handler to this attachment
    attachementBodyPart.setDataHandler(new DataHandler(source));
    // Set the filename
    attachementBodyPart.setFileName(filename);
    // Add this part
    multipart.addBodyPart(attachementBodyPart);
    // Put parts in message
    message.setContent(multipart);
    // Send the message
    Transport.send(message);

  • How to receive HTML email using JAVA Mail API?

    Hello!
    I am developing WEB Mail System. There is a little problem. I am unable to receive mail in HTML format. The mail is being received in only text format currently. What method do i need to use to achieve this functionality currently i am using
    MimeMessage message = mail.getMessage();
    if(message.isMimeType("text/plain")){
    String str_message_body = message.getContent().toString();
    else
    Multipart multipart = (Multipart)message .getContent();
    Kindly advise me regarding that because i am in a state of fix right now and unable to proceed further.
    I will really appreciate a prompt response from you.
    Regards,
    Burhan Ramay.

    HTML is a text format too, so you do
    if(message.isMimeType("text/html")){
    String str_message_body = message.getContent().toString();
    }

  • Using Java Mail API from Tomcat

    Hello,
    Purely as an academic exercise I have written a JSP page which, upon being requested from the client's browser, should send me a default email using Java Mail Api.
    here is the code :
    import java.util.*;
    import java.io.*;
    import javax.mail.*;
    import javax.mail.internet.*;
    import javax.activation.*;
    public class TestMail {
        static String msgText1 = "success this time 12";
        static String msgText2 = "This is the text in the message attachment.";
        public String sendIt() {
            String to = "<my email";
            String from = "<anything>";
            String host = "<my ip address of smtp server>";
            boolean debug = false;
            Properties props = new Properties();
            props.put("mail.smtp.host", host);
            Session session = Session.getInstance(props, null);
    .....The code works fine as a stand alone app but when called from JSP page it hangs on the Session.getInstance line. I can only guess that this might be a security issue with the container not allowing access to the smtp server ?
    Can anyone give me a clue ???

    Your Tomcat log files should spell out the problem for you.
    My Tomcat installation does not come with the Java Mail API. I had to add the mail and activation jar files to the server/common.lib directory (or the server's shared/lib or the WEB-INF/lib of your application.)
    HTH.

    You can use InitialContext ic = new InitialContext() only if you are using a startup class, servlet or a JSP i.e
    server side code.
    If you are using a java client you need to use Context ic = getInitialContext();
    Try this code
    import java.util.*;
    import javax.activation.*;
    import javax.mail.*;
    import javax.mail.internet.*;
    import javax.naming.*;
    import java.io.*;
    import java.net.InetAddress;
    import java.util.Properties;
    import java.util.Date;
    public class MailTo {
    public static void main(String args[])
    try {
    Properties h = new Properties();
    h.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
    h.put(Context.PROVIDER_URL, "t3://localhost:7001");
    Context ic = new InitialContext(h);
    Session session = (Session) ic.lookup("testSession");
    Properties props = new Properties();
    props.put("mail.transport.protocol", "smtp");
    props.put("mail.smtp.host", "XX.XX.XX.XX");
    props.put("mail.from", "[email protected]");
    Session session2 = session.getInstance(props);
    Message msg = new MimeMessage(session2);
    msg.setFrom();
    msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse("[email protected]",false));
    msg.setSubject("Test Message");
    msg.setSentDate(new Date());
    MimeBodyPart mbp = new MimeBodyPart();
    mbp.setText("This is a mail sent to you using JAVA Mail API and Weblogic Server");
    Multipart mp = new MimeMultipart();
    mp.addBodyPart(mbp);
    msg.setContent(mp);
    Transport.send(msg);
    catch(Exception e)
    e.printStackTrace();

    one important thing-----
    Create a dir under PORTAL-INF and import the following jars-- activation.jar, mail.jar,imap.jar,smtp.jar, mailapi.jar.
    This works..

  • Using java mail api without servlets, I ve sent an html mail.  In that Ive

    Using java mail api without servlets, I ve sent an html mail. In that Ive specified action to the servlet. On click, it shows url as file:///C:/Documents%20and%20Settings/sirivanig/Local%20Settings/Temporary%20Internet%20Files/Content.IE5/CNFHMDIT/updatemailerform%5B2%5D.htm instead of www.servername.com/....
    May I know the reason why it shows like this.
    Do I ve to send htmlmail through servlet so that it does show proper url?

    Possibly your mailer is restricting your access to URLs to prevent
    various scams. Without the details, it's hard to know what's going
    wrong.
    Have you tried with a different mailer?

  • How to do SAVE AS DRAFT using java mail api

    Hello,
    I want to know how to do SAVE AS DRAFT using Java mail Api.
    thanks

    Hello,
    I want to know how to do SAVE AS DRAFT using Java
    mail Api.
    thanksI don't think you can. That sounds like a feature of a mail client app itself. The Java mail API is for when you're ready to actually send the thing. Saving drafts is storing them somewhere like you would any other data; nothing to do with the mail API.

  • Can i use java mail APIs to read Unix mail

    hi
    can i use java mail APIs to read Unix mail?
    Unix has "mail" command which can be used to access mails on the Unix system.
    is it possible to execute mail & access unix mails remotely using POP/IMAP
    thanks in advance

    There are JavaMail providers that allow you to access the Unix mail spool files directly. Alternatively the standard JavaMail API can access a POP or IMAP server, if one is installed.

  • How to use Java Mail API in Unix

    I am trying to write some code using Java mail API. I want to execute it in Unix. I downloaded the mail API to windows machine and ftped the mail.jar file to a Unix machine. Then I set the class path as below:
    export CLASSPATH=$CLASSPATH:/home.../mail.jar
    Then I tried to compile my Java program. The output is as below:
    error: error reading /home.../mail.jar; invalid END header (bad central directory offset)
    mail.java:1: package javax.mail does not exist
    import javax.mail.*;
    Can any one please help me out.

    You should also include the "activation.jar" file that you obtained from
    downloading the Java Activation Framework, in your CLASSPATH.
    For example:
    export CLASSPATH=$CLASSPATH:/urPath/activation/activation.jar
    Besides, assuming you unzipped javamail-1_4_1.zip in home/download the following should work
    export CLASSPATH=$CLASSPATH:home/download/javamail-1.4.1/mail.jar:.

  • Error while sending mail when using Java Mail API

    Hi Experts,
    I am trying to execute a webdynpro application which uses the Java Mail API to send emails. The exception that I get on executing the application is :
    Sending failed;  nested exception is: javax.mail.SendFailedException: Invalid Addresses;  nested exception is: javax.mail.SendFailedException: 550 5.7.1 Unable to relay for [email protected]
    Can anybody please help me sort out the issue.
    Regards
    Abdullah

    Hi,
    Usually one get this error if the SMTP server is configured not to relay mails (a security measure) or the SMTP server need the mail to be sent from a trusted IP or with proper authentication. Some SMTP servers are configured to block junk mails.
    Pls check with your  mail server administrator.
    Regards
