why the reply mail is sent as attachment when I send it to outlook account using javamail?

I tried in many ways to get the reply in same thread using outlook account and javamail api but iam not able to get reply in same thread instead iam getting as attachment.
I tried to copy whole content and save in current message even then iam getting as attachment, also tried to change the content disposition as inline still it didn't work
you can find the code below which i had tried.
Properties properties = new Properties();
Session emailSession = Session.getDefaultInstance(properties,null);
store = emailSession.getStore("imaps");
store.connect(host,mailbox_username, mailbox_password);
folder = store.getFolder("Inbox");
folder.open(Folder.READ_WRITE);
Message[] unreadMessages = folder.search(new FlagTerm(new Flags(Flags.Flag.SEEN),false));
if(unreadMessages.size()>0)
{
for (int i = 0; i < unreadMessages.length; i++)
{
log.info("retriving message "+(i+1))
Message message = unreadMessages[i]
Address[] froms = message.getFrom();
String senderEmailAddress =(froms[0]).getAddress();
if(senderEmailAddress.endsWith("#gmail.com"))
{
subject = message.getSubject()
log.info(message.getSubject())
}
else
{ //reply to same mail here we need to reply to the message
Message message2 = new MimeMessage(emailSession);
message2= (MimeMessage) message.reply(false);
message2.setSubject("RE: " + message.getSubject());
//message2.setFrom(new InternetAddress(from));
message2.setReplyTo(message.getReplyTo());
message2.addRecipient(Message.RecipientType.TO, new InternetAddress(senderEmailAddress));
BodyPart messageBodyPart = new MimeBodyPart();
content = "some reply message"
//multipart.addBodyPart(content);
messageBodyPart.setText(content);
Multipart multipart = new MimeMultipart("related");
multipart.addBodyPart(messageBodyPart);
messageBodyPart = new MimeBodyPart();
//messageBodyPart.setDataHandler(message.getDataHandler());
//bodyPart.setDataHandler(new DataHandler(ds));
//messageBodyPart.setHeader("Content-Type", "image/jpeg; name=image.jpg");
//messageBodyPart.setHeader("Content-ID", "<image>");
//messageBodyPart.setHeader("Content-Disposition", "inline");
//messageBodyPart.addBodyPart(bodyPart);
//msg.setContent(content);
messageBodyPart.setDisposition(MimeBodyPart.INLINE);
messageBodyPart.setContent(message, "message/rfc822");
messageBodyPart.setDataHandler(message.getDataHandler());
// Add part to multi part
multipart.addBodyPart(messageBodyPart);
// Associate multi-part with message
message2.setContent(multipart);
Transport t = emailSession.getTransport("smtp");
try {
t.connect(mailbox_username, mailbox_password);
t.sendMessage(message2, message2.getAllRecipients());
} finally {
t.close();
}
}
}
}

"inline" vs. "attachment" is just advice for the mail reader. Many ignore the device, or aren't capable of displaying all content types inline.
If you want the text of the original message to appear in the body of the reply message (e.g., indented with ">"), you need to extract the original text and reformat it appropriately, adding it to the text of the reply, then set that new String as the content of the reply message.

JavaMail MimeBodyPart is not being added to MimeMultipart "properly"

Let it be clear that Java is working correctly. The problem is with the programmer!
I need to add 3 attachments to an email (1 zip, 1 png, 1 jpeg). Initially I wrote code that can add each item on it's own - and it works. Then to add all 3 items at the same time I took the same code (with very minor modifications) and put it in a for loop. This is where I am having an issue. The loop adds 3 attachments to the email, but the problem is that all the attachments are same identical attachment. Specifically, the first two attachments that should be attached in the first 2 iterations of the for loop are not attached, and the third attachment (the attachment that is up to bat at the third iteration) is attached 3 times.
I read the Java docs, I tried all kinds of changes and I am having a hard time understanding where I am going wrong. The reality is that I don't have enough programming ability to move forward. I'm stuck. Any advice would be greatly appreciated! I attached most of the class, but the real problem is in the for loop - why are all 3 unique objects not being attached?
Thanks in advance.
try
{
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(userLogin));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(primaryRecipient));
MimeBodyPart bodyPart = new MimeBodyPart(); //container to hold the email contents (body only - the text)
bodyPart.setText(emailBody);
MimeMultipart multipart = new MimeMultipart();
multipart.addBodyPart(bodyPart);
MimeBodyPart mimePart = new MimeBodyPart();
String filename; //hold the current path
FileDataSource resource;//object to grab the physical resource
for(int i = 0; i < itemsToAttach.length; i++)
{
filename = itemsToAttach[i];
System.out.println("Test: " + itemsToAttach[i]);//#############################test only
resource = new FileDataSource(filename);
mimePart.setDataHandler(new DataHandler(resource));
mimePart.setFileName(filename);//###########fix the long ugly name
multipart.addBodyPart(mimePart);
System.out.println("multipart contents: " + multipart.toString());
}
message.setContent(multipart);
message.setSubject(emailSubject);
Transport.send(message);
System.out.println("Sent message successfully....");
}
catch (MessagingException e)
{
throw new RuntimeException(e);
}
The output looks like this:
The file is present!
Sending cc to: mikexxxxxxx#hotmail.com
Sending bcc to: mikexxxxxx#gmail
Test: C:\Users\Mike\workspace\Z_ToTransfer\Assig4_SendEmails\part2_send_email_with_attachment\attachments\test attachments.zip

Sent message successfully....

Looks like you are reusing the same object and it is getting overwritten on every iteration of the loop. Thant's why the only entry persists is the last mimepart when you send the message:
You can do following:
Create a different object of MimebodyPart for every new file:
MimeBodyPart[] mimePart = new MimeBodyPart[itemsToAttach.length];
String filename; //hold the current path
FileDataSource resource;//object to grab the physical resource
for(int i = 0; i < itemsToAttach.length; i++)
{
mimePart[i] = new MimeBodyPart();
filename = itemsToAttach[i];
System.out.println("Test: " + itemsToAttach[i]);//#############################test only
resource = new FileDataSource(filename);
mimePart[i].setDataHandler(new DataHandler(resource));
mimePart[i].setFileName(filename);//###########fix the long ugly name
multipart.addBodyPart(mimePart[i]);
System.out.println("multipart contents: " + multipart.toString());
}

Java - Send an email : image / HTML and PDF attachment

Thank you for reading my post.
I need to automatically send emails which contain:
a company logo (an image),
an HTML message,
a PDF attachment.
I do not manage to have both the image displayed properly in the email, and the PDF "managed properly" by the email client.
CASE 1
(See code below) With multipart = new MimeMultipart("mixed");
the PDF attachment is managed properly by the email client:
a little paper clip appears in the email client to indicate that email has an attachment,
the size of the PDF attachment appears too,
etc.
the logo isn't displayed properly at the top of the email (within the HTML code) but at the end of the email.
CASE 2
(See code below) When multipart = new MimeMultipart("related");
This is the reverse:
the image is displayed at the top of the email where it is supposed to be,
but the PDF attachment is not properly handled by the email client (no paper clip in the main windows, "size unknown" for the attachment, etc.).
I regularly receive emails which contain both a logo and a PDF attachment (as most of us do).
I have noticed (in the messages source of these emails) that there usually are two parts: one multipart/mixed and one multipart/related.
I do not manage to write the code for which both the logo and the attachment are handled properly by the email client.
Below you can find the code I already wrote.
Thank you for helping and best regards.

Sending an email with inline picture on App Engine since 1.9.0

I am currently trying to send an email with a picture inside the mail using the Google App Engine 1.9.5. This features is availible only from the version 1.9.0 of the SDK :
Users now have the ability to embed images in emails via the Content-Id attachment header.
https://code.google.com/p/googleappengine/issues/detail?id=965
https://code.google.com/p/googleappengine/issues/detail?id=10503
Source : https://code.google.com/p/googleappengine/wiki/SdkForJavaReleaseNotes
This is my code :
Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress("leo.mieulet#xxx.com", "xxx.com newsletter"));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress("leo.mieulet#xx.com", "Leo Mieulet"));
msg.setSubject("Inline image test : "+new Date().getTime());
String imageCid = "graph";
DataSource ds = new ByteArrayDataSource(imageBase64, "image/png");
MimeBodyPart imagePart = new MimeBodyPart();
imagePart.setDataHandler(new DataHandler(ds));
imagePart.setFileName(imageCid + ".png");
imagePart.setHeader("Content-Type", "image/png");
imagePart.addHeader("Content-ID", "<" + imageCid + ">");
String htmlBody = "My html text... <img src=\"cid:"+imageCid+"\"> ... ends here.";
// Create alternate message body.
MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent("<html><body>"+htmlBody+"</body></html>", "text/html");
final Multipart multipart = new MimeMultipart();
multipart.addBodyPart(htmlPart);
multipart.addBodyPart(imagePart);
msg.setContent(multipart);
msg.saveChanges();
Transport.send(msg);
I receive an email which looks like :
Could anyone help me with the problem ?

Based on the imageBase64 variable name, you seems to give to the ByteArrayDataSource the image already encoded in Base64. You should directly use the image byte array without Base64.encode() it.

Awesome ! ;)
If you want to display the image in pure HTML ( in app-engine doGet() context ) :
//byte[] imgContent = the content of your image
Base64 base64 = new Base64();
imgContent = base64.encode(imgContent);
resp.getWriter().write("<html><img src='data:image/png;base64,"+new String(imgContent)+"'></html>");
And as said #benoit-s, you don't need to encode in base64 the content of your image.
I just edited this line :
DataSource ds = new ByteArrayDataSource(imageBase64, "image/png");
to
//byte[] imageAsByteArray = the content of your image
DataSource ds = new ByteArrayDataSource(imageAsByteArray, "image/png");

Reading mails sent from GMail

I am using JavaMail to read mail in my Android app. I have tried to cover all combinations i.e Mail sent/received on/from Custom Server/Gmail ID/Live ID.
The problem occurs with SOME of the mails sent from GMail WITH Attachment. I am able to receive the attachment, but the content returns javax.mail.internet.MimeMultipart#44f2e698
Here's the code used to receive and read messages:
Properties props = System.getProperties();
props.setProperty("mail.store.protocol", "imap");
try {
/* Create the session and get the store for read the mail. */
Session session = Session.getInstance(props, null);
Store store = session.getStore("imaps");
store.connect("imap.gmail.com", Username, Password);
/* Mention the folder name which you want to read. */
Folder inbox = store.getFolder("INBOX");
System.out.println("No of Unread Messages : " + inbox.getUnreadMessageCount());
/* Open the inbox using store. */
inbox.open(Folder.READ_ONLY);
Message messages[] = inbox.getMessages();
Log.d("Inbox", "Message Count: "+inbox.getMessageCount());
for (int i = messages.length - 1 ; i > 0; --i) {
Log.i("ContentType", "ContentType: "+messages[i].getContentType());
Object msgContent = messages[i].getContent();
String content = "";
/* Check if content is pure text/html or in parts */
if (msgContent instanceof Multipart) {
Multipart multipart = (Multipart) msgContent;
Log.e("BodyPart", "MultiPartCount: "+multipart.getCount());
for (int j = 0; j < multipart.getCount(); j++) {
BodyPart bodyPart = multipart.getBodyPart(j);
String disposition = bodyPart.getDisposition();
if (disposition != null && (disposition.equalsIgnoreCase("ATTACHMENT"))) { // BodyPart.ATTACHMENT doesn't work for gmail
System.out.println("Mail have some attachment");
DataHandler handler = bodyPart.getDataHandler();
System.out.println("file name : " + handler.getName());
}
else {
System.out.println("Content: "+bodyPart.getContent());
content= bodyPart.getContent().toString();
}
}
}
else
content= messages[i].getContent().toString();
What I know about the problematic mails:
getFrom also return the name i.e it comes in this format FirstName LastName &ltemailID#gmail.com&gt
MultiPart contains 2 BodyParts:
BodyPart 1 returns the content as javax.mail.internet.MimeMultipart#44f2e698
BodyPart 2 returns the correct name for attachment

BodyPart 1 returns the content as
javax.mail.internet.MimeMultipart#44f2e698
Try calling getBodyPart on the MimeMultiPart
That probably returns a MimeBodyPart you can call getContent() on
http://docs.oracle.com/javaee/5/api/javax/mail/internet/MimeBodyPart.html#content

You're probably only handling the simplest case of a text message with attachments. MIME allows much more. You need to learn about the difference between multipart/mixed, multipart/alternative, multipart/related, and multipart/signed. The JavaMail FAQ has more information on handling attachments and the msgshow.java demo program included with the JavaMail download bundle shows how to process messages with nested multiparts.
