[appengine-java] Re: Can't send mail with attachment using JavaMail API

[mably]

Of course, here is below my email relay servlet class.  What I'm
willing to do is to hide my customers email addresses by relaying
email to them via my google app email adress.

I would like to be able to relay html emails with images which is
quite common nowadays.  I am sending my test emails from a gmail
account.

Thanx for your help.

Hi Ikai, have you been able to reproduce my "Converting attachment
data failed" exception ?

I'm still stuck on this strange bug.

Thanx for your help.

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[mably]

Hi Ikai, thanx for you help.

I've copy pasted your code on my webapp (webwinewatch), I've no error
but the mail isn't correctly relayed, all attachements are removed.

I've just modified the sender, from and recipient lines :

message.setSender(new InternetAddress("@gmail.com", "Relay
account"));
message.setFrom(message.getSender());
message.setRecipient(Message.RecipientType.TO, message.getSender());

Do you have any clue ?

You can test it, sending an email to : contact-
t...@webwinewatch.appspotmail.com

Thanx again for your help.

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[mably]

In fact standards attachments works.

But it's not what I'm trying do do.

I'm need to relay HTML messages with inline images and this is still
not working.

Is it a kind of limitation of GAE or is it supposed to work ?

Thanx for your help.

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[mably]

I'm just sending a simple mail from my Gmail account with an embedded
gif image.

I can perfectly read it from my mail servlet handler but when I try to
relay it (cf. code from first message) I get this annoying "Converting
attachment data failed" error which seems to be specific to GAE.

Here is the mail sent data :

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[mably]

I've written a simple class sending an HTML email with an embedded
image (cf. below) via GMail SMTP.  It works perfectly fine when run
locally from Eclipse.

The same code in a GAE mail servlet handler produce the infamous
"Converting attachment data failed" error.

So it really seems to be a problem in GAE javamail implementation.

Of course, the code above doesn't need to be run in mail handler
servlet :-)

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[mably]

I haven't found a way to set a Content-ID header on a mimebodypart/
attachment using the low-level API.  The MailService.Attachment class
is quite rudimentary (only filename and data).

May be some part of the low level API are still undocumented ?

Thanx for all.

Any chance to see this bug fixed in the future ?

Is there any documentation on the meaning of "Converting
attachment data failed" error message ?

By the way, do you know if Google plans to open source some parts of
GAE librairies so we could investigate deeper when we encounter such a
problem ?

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[Don]

Hi Ikai,

I tried your example code, but I cannot attach an image on the email
that I send.
There is no conversion error either.

Here is snippets of the code, please help..

//Retrieving image:
URL url = new URL("http://stockcharts.com/c-sc/sc?s="; + ticker +
"&p=DAILY&b=5&g=0&i=0&r=3528");
//Sending mail
SendMail sendmail = new SendMail(customerEmail, url.openStream());

// send mail function
public SendMail(String recipient, InputStream imagestream) {
msg.setFrom( new InternetAddress("lydonchan...@gmail.com", "dons
service"));
msg.addRecipient(Message.RecipientType.TO, new 
InternetAddress
(recipient));
msg.setSubject("dons service daily charts");

Multipart multipart = new MimeMultipart();

MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent(" url2: " , "text/html");
multipart.addBodyPart(htmlPart);

// append png image?
ByteArrayDataSource mimePartDataSource = new 
ByteArrayDataSource
(imagestream, "image/png");

MimeBodyPart attachment = new MimeBodyPart();
attachment.setDataHandler(new 
DataHandler(mimePartDataSource));
attachment.setFileName("ticker.png");
multipart.addBodyPart(attachment);
msg.setContent(multipart);

Transport.send(msg);
}

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[Don]

Thanks Ikai.

It did NOT work before because I set the dataHandler before I set the
FileName.

Just have to set the FileName and then set the DataHandler.
attachment.setFileName("ticker.png");
attachment.setDataHandler(new DataHandler(mimePartDataSource));

Is this behaviour intentional?

Many thanks
Don

Hi Ikai,

So does the order of setDataHandler + setFileName cause problems as I
wrote above?

Hi there,

I reproduced same problem.
I cannot send attachment file and inline image with HTML mail.
(Of course, I could send plain text mail without attachment and
 HTML mail without inline image)
I don't have any idea.  It would be very helpful to tell me anything.

I build the mime message in HtmlMimeMessage#createMimeMessage method.

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[minor-undroid]

Sorry, I made a wrting mistake.

I cannot send the HTML mail with inline image,
and cannot send the HTML mail with attachement file, too.
(I could send the plain text mail with an attachment image
 and HTML mail without attachment file)

I think It's only GAE's problem.
Do you have any idea?

Re: [appengine-java] Re: Can't send mail with attachment using JavaMail API

[Ikai L (Google)]

I couldn't reproduce your exact error, but I was able to put together a
working example of an inbound email handler to relay messages. I'm going to
expand the documentation about processing inbound emails. Here's some
working code: http://pastie.org/701517

Does this example help any? Code is also pasted below, but it'll be easier
for you to look at the Pastie.

Logger.getLogger(MailHandlerServlet.class.getName());

private static final String SENDER = "sen...@google.com";


protected void doPost(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);
try {
MimeMessage message = new MimeMessage(session,
request.getInputStream());

Object content = message.getContent(); // You could also
probably just use message.getInputStream() here
   // and avoid the
conditional type check

if (content instanceof String) {
log.info("Received a string");
} else if (content instanceof InputStream) {
// My somewhat limited testing indicates that this is always
getting returned as an
// InputStream

InputStream inputStream = (InputStream) content;
ByteArrayDataSource inboundDataSource = new
ByteArrayDataSource(inputStream, message.getContentType());
Multipart inboundMultipart = new
MimeMultipart(inboundDataSource);

// Set the body with whatever text you want
Multipart outboundMultipart = new MimeMultipart();
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText("Set your body here");
outboundMultipart.addBodyPart(messageBodyPart);

// Loop over the multipart message coming in and
// append them to the outbound Multipart object
for (int i = 0; i < inboundMultipart.getCount(); i++) {
BodyPart part = inboundMultipart.getBodyPart(i);
/*
The content-disposition header is optional:
http://www.ietf.org/rfc/rfc1806.txt

a MIME part.
*/
if(part.getDisposition() == null) {
// This is just a plain text email
} else {
// We have something interesting. Let's parse it.

// Create a new ByteArrayDataSource with this part
MimeBodyPart inboundMimeBodyPart = (MimeBodyPart)
part;
InputStream is = part.getInputStream();
ByteArrayDataSource mimePartDataSource = new
ByteArrayDataSource(is, inboundMimeBodyPart.getContentType());

// Create a new outbound MimeBodyPart and set this

MimeBodyPart outboundMimeBodyPart = new
MimeBodyPart();
outboundMimeBodyPart.setDataHandler(new
DataHandler(mimePartDataSource));


outboundMimeBodyPart.setFileName(inboundMimeBodyPart.getFileName());
outboundMultipart.addBodyPart(outboundMimeBodyPart);

}

}
message.setContent(outboundMultipart);

}
message.setFrom(new InternetAddress(SENDER, "Relay account"));
message.setRecipient(Message.RecipientType.TO, new
InternetAddress(RECIPIENT, "Recipient"));

Transport.send(message);

} catch (MessagingException e) {
throw new ServletException(e);
}
}
}

François,

I'm not familiar with any standards with regard to inline images. Do you
have this working outside of App Engine? Do you have working code from that?
If there are discrepancies in our implementation of javax.mail.* and
standard implementations we should be aware.

What I mean is, is this code working on a different mail server?

Re: [appengine-java] Re: Can't send mail with attachment using JavaMail API

[Ikai L (Google)]

That's good information to know. We are not using Sun's JavaMail
implementation, so it's possible there are points of incompatibility.
There's one last thing you may want to try:

http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/mail/package-summary.html

The above page documents the Low-Level API. Try creating an email object via
that API, setting the Content-ID of the attachment and the HTML tag to point
to the cid. You're already doing that in the example you sent using
javax.mail, but I'm wondering if the low-level API is capable of doing this.
If not, I'll open an issue.

Re: [appengine-java] Re: Can't send mail with attachment using JavaMail API

[Ikai L (Google)]

Looks like you're right. As far as I know there are no hidden methods.

Another workaround for this limitation could be to store incoming images in
the data store on an incoming email, then reference them in the emails that
get sent out. It's not ideal, but it may be the solution to what you are
looking for.

Re: [appengine-java] Re: Can't send mail with attachment using JavaMail API

[Ikai L (Google)]

We'll always try to open source what makes sense. I'm not sure it'd make
sense to open source all GAE libraries since many of the calls talk to
services. The javax.mail.* could fall under the "makes sense" category.

Re: [appengine-java] Re: Can't send mail with attachment using JavaMail API

[Ikai L (Google)]

Interesting, so this did not work?

attachment.setDataHandler(new DataHandler(mimePartDataSource));
attachment.setFileName("ticker.png");

I'll need to do some research into the Java mail spec to see if we are
matching it. Could be a bug if we aren't.
