Multipart/mixed MIME

I am working on a B2B type servlet. The servlet needs to be able to handle the splitting up of a multipart/mixed MIME message into its various components. The components are delimited by boundaries and http content headers. Is there any JAVA class out there that can handle this ? I saw a MultiPart class that is part of javax.mail package, but it looks like you need a mail session to use it. My servlet will be just receiving http messages.
Any help would be greatly appreciated.

john,
how did u solve this?
I'm doing byte by byte comparision of incoming response stream to construct different parts.....i'm wondering if there is any more effecient method..
Thanks,

Multipart/mixed mime problems with mail

So from what I've gathered Mail has problems with multipart/mixed mime type emails.
I wrote a PHP script that sends customers their orders as a PDF attachment as well as the order processing department.
If Mail doesn't support multipart/mime what is the alternative to use in my mime type to make my emails work?
Is there another content type that I should be using?

Unable to read email content of type multipart/mixed....

Hi i have written following code to read text content form the multipart email content type,
but when i say
if (content instanceof Multipart){
System.out.println("############ Content Type is Multipart ############ ");
messagePart = ((Multipart) content).getBodyPart(0);
}the flow is not going into the if condition,
bellow is the detailed code and the output in the console, you can check with the SOPs
Part messagePart = message;
content = messagePart.getContent();
System.out.println("############ : " + content);

Multipart/mixed content: html, pdf

Hi.
I have a problem sending multipart content back to a browser through the response object.
What I want is to send a "Please be patient" html page while a pdf is created and send it as a second part as soon as it is created and can't get it to work.
The problem is, the pdf just does not show up. The html sent first is removed from display, the plugin starts but then nothing happens and I end up with a blank browser window.
Code snippet:
response.setContentType( "multipart/mixed;boundary=" + boundary );
ServletOutputStream outStream = response.getOutputStream();
response.addHeader( "MIME-Version", "1.0" );
outStream.println( "" );
outStream.println( "--" + boundary );
response.addHeader( "Content-Type", "text/html" );
response.addHeader( "Content-Transfer-Encoding", "chunked" );
outStream.println( "" );
outStream.println( "<html>" );
outStream.println( "<head><title>Supplier Info</title></head>" );
outStream.println( "<body>" );
outStream.println( "<p>Please be patient...</p>" );
outStream.println( "</body></html>" );
outStream.println( "" );
outStream.println( "--" + boundary );
outStream.flush();
// create pdf and write it into a byte array called 'result'
response.addHeader( "Content-Type", "application/pdf" );
response.addHeader( "Content-Transfer-Encoding", "chunked" );
response.addHeader( "Content-Disposition", "inline" );
outStream.println( "" );
System.out.println( "result.length: " + result.length ); //result contains data!
outStream.write( result );
outStream.println( "" );
outStream.println( "--" + boundary + "--" );
outStream.println( "" );
outStream.flush();
Please could somebody tell me what's wrong with my code? Am I missing something?
My environment is Win2k, Borland JDev 3.2.3, Mozilla 1.0.
TIA

try this
Response.reset()
before setting the content type

CFMAIL Attached vs. embedded (cfmail, multipart/mixed)

I want to send a mail which has a PDF attachment and an embedded image. When I send them both with cfmailparam (with correct disposition) they arrive in the email as attachments in the body...you don't get the little email paperclip attachment icon.
When I tried using mimeattach for the PDF it did work!...but the image denoted with cfmailparam also came through like that. So I looked the email headers of both and the good one was Content-Type: multipart/mixed; while the bad one was "multipart/related".
So how can I make cfmailparam send it as multipart/mixed? (if that's even the right question...maybe I should stick with mimeattach and do something else?)
Thanks Folks' - Randy

Can't read Messages with Content-Type multipart/mixed

For many years I have used „QuickMail Pro“, as my favorite Mail-Client. Now I had switch to Apple Mail. I hoped, to be more compatible to other „modern“ Mail-Clients. So could it be, that Apple Mail can not read Messages from Type <multipart/mixed>? I only see the Header-Information and instead of the Message-Text there is only an Error-Message:
<Diese E-Mail kann aufgrund ihrer Formatierung nicht angezeigt werden. Bitten Sie den Absender, Ihnen die E-Mail erneut in einem anderen Format bzw. mit einem anderen E-Mail-Programm zu senden.
multipart/mixed>
Did anyone know a simple Way, to read this Messages.
My old QuickMail has no Problem with this Type.

Hi Ruchi,
You need to use Java Mapping or UDF to create Multipart/Mime

Is it possible to create a multipart/alternative in a multipart/mixed email

Hi,
does somebody know how can I build a multipart/mixed email in which one of the parts is a multipart/alternative on its own? I cannot figure it out.
Multipart has addBodyPart(BodyPart part) to add parts, but the added part cannot be a multipart from what I see, am I missing something?
thanks in advance

Today we rely on Simulink to perform parameterization of your designs in two ways:
Parameterizable Subsystems and Blocks : Parameters themselves can be MATLAB expressions that need to be evaluated for which we need the MATLAB interpreter
The very useful Rate and Type propagation or Simulink compilation that allows us to specify types & rates in one location that gets systematically propagated to all.
To truly make the HDL Netlist that is generated from SysGen parameterizable, we would have to implement some of this capability in the HDL netlist itself by:
Using Generics(VHDL) or Parameters(Verilog) - We would have to capture the bit width(type) propagation through levels of hierarchies and finally parameterize the IP itself based on this value
Since IP itself does not have this capability through generics, we would have to package a separate tcl script that updates the IP parameterization appropriately in response to top level parameters(or GUI parameters)
Interpreting MATLAB expressions and translating them into VHDL/Verilog expressions (alternatively tcl expressions of IP). In simulink, mask parameters can be passed from one level to the next. Also parameterization of a block can be composed of Matlab expressions using variables from ancestor masks & the MATLAB interpreter – so we will need to somehow capture that as well.

Multipart/mixed and multipart/relative Content type probs

I tried to create a page from a servlet by using the multipart/mixed
          Content-type.
          All that is displayed inside the browser is the actual code including the
          headers for the single parts of the page. I also checked it on the byte
          level, getting the same results.
          Does anybody have an idea ?
          Thank you very much ,
          Tom


Are you setting the content type prior to each response (i.e.
          out.println("Content-type: text/html\n");)?
          Below is an example (untested, but should work):
          // Global constants
          static final String BOUNDARY_STR ="Joe";
          static final String BOUNDARY = "--"+BOUNDARY_STR;
          static final String BOUNDARY_END = BOUNDARY+"--";
          // Inside of doGet
          res.setContentType("multipart/mixed;boundary="+BOUNDARY_STR);
          ServletOutputStream out = res.getOutputStream();
          // First Response
          out.println(BOUNDARY);
          out.println("Content-type: text/html\n");
          out.println("<html>\n");
          out.println("<head>\n");
          out.println("<title>First Response</title>\n");
          out.println("</head>\n");
          out.println("<body>\n");
          out.println("<h1>First Response</h1>\n");
          out.println("</body>\n");
          out.println("</html>\n");
          out.println(BOUNDARY);
          out.flush();
          // Second Response
          out.println(BOUNDARY);
          out.println("Content-type: text/html\n");
          out.println("<html>\n");
          out.println("<head>\n");
          out.println("<title>Second Response</title>\n");
          out.println("</head>\n");
          out.println("<body>\n");
          out.println("<h1>Second Response</h1>\n");
          out.println("</body>\n");
          out.println("</html>\n");
          out.println(BOUNDARY);
          out.flush();
          // Done
          out.println(BOUNDARY_END);
          out.flush();

Support for multipart/mixed on iOS Mail

I subscribed what here is called "Certified Electronic Mail" (italian: PEC - Posta Elettronica Certificata), which has the same value as registered mail.
When I receive an email, I can see all the metadata, but not the message itself, which should be an .eml attachment.
In the footer there's only a message which tells (it's a translation): "This message cannot be shown because of the format used. Ask the sender to send it again using a different format and/or a different email client.
multipart/mixed".
Is it true that iOS cannot read multipart/mixed messages?
My PEC provider uses this format only.
Thank you.

Hi Paolo,
I work for an IT company whose focus is on mailing and PEC systems, so after reading your post I've done some tests with my own PEC accounts.
I've noticed that iOS (test platform was 4.3.3 on an iPhone4) has indeed some problems in reading PEC messages, and this seem to be connected with the multipart/mixed content-type. If you do a quick search in the forums, you will find that this type is infact not supported by iOS , and this is why we are getting the error. During my tests, depending on the PEC Provider that hosted the sender, I got different behaviours: sometimes I didn't get any error at all, but still I was unable to see the postacert.eml attachment containing the text of the original message.
Unfortunately the PEC regulations in Italy force the provider to build the message using this multipart/mixed structure, so I guess we will not be able to read PEC messages on our iPhones until Apple fix this.
By the way, I am going to do some more tests to understand why I am getting such different results depending on the provider. I'll keep you updated should I find a workaround.

Why isn't multipart/mixed supported in Mail?

If I'm not mistaken multipart/mixed content types aren't supported in Mail.app and I'm told I should be using multipart/alternative despite the difference in the actual content for each part. In my case I have some text content and an rfc822 context so I figure I'm typing the thing correctly since Mail.app under OSX displays the rfc822 inline but the phone's Mail client simply complains.

Just wanted to echo this post. Given that a lot I people keep on sending multipart/mixed messages, I have to say that simply not displaying them is very disappointing.
The problem is that there are no alternatives whatsoever. Ok mail.app does not support it, but at least let the user download the source. I had my electronic tickets sent to me in such a message and had to figure out how the henk and when I can get my fligt having a dumb mail.app telling me that it won't download the rest. Come on!!! That's so frustrating.
In my experience about 10% of mails are multipart mixed. Do you see me telling to my customers to use another mail programme? Please improve this one.

Mail Problem with multipart/mixed Content, "empty mails" via IMAP

I do need some help.
Here is my setup. I have a OSX Mountain Lion Server with the mail service running. fetchmail is collecting mail from a pop account. I have two Mac clients - one with Outlook for Mac, one with Apple Mail,
Everything is fine exept...
... if I receive a mail from an Exchange Server with a PNG-Image in the signature (e.g. a company logo) then...
... this mail will be displayed as an empty mail. Correctly spoken, the mail header is there, but the mail body ist not shown. The body is there - I can see it if I swich to the raw view in mail.
So I tried to figure out what the reason might be. I also tried several ideas from other discussions here - without success.
This error is concerning only mails with the Content-Type: multipart / mixed - coming from Exchange Servers. The mail body is not displayed. It seems to be that something is corupptung the IMAP Envelope of these mails.
- Is it a security problem?
- Is it a filtering problem?
- Is it a settings problem in Apple Mail and Outlook for Mac?
- Is it a settings problem in fetchmail?
I don't know... I think it is a settings problem in the main.cf - but I don't know what to do.
Can anybody help???
Kind regards,
Robert.

Problem solved!
It was a bug in fetchmail. Try out the version 6.3.26. You have to compile fetchmail yourself... it is not a great thing. And everything is working.

Difference between multipart/mixed and alternative or ralted

Can anyone tell me what's the difference between multipart/mixed and /alternative and ralted .
How the parse method works ?
Thanks a lot .

The "multipart/alternative" type is syntactically identical to "multipart/mixed", but the semantics are different. In particular, each of the body parts is an "alternative" version of the same information.

I am working on proxy to Mail scenario, wherein Pi is receiving data from SAP over proxy, creating a csv of the data and sending it to recipient as the email with the attachment.
The User is saying that he wants the email content type as Multipart MIME format. I have searched on SDN and web, but couldnu2019t find how to implement in PI.Please provide your inputs.
Thanks in advance,
Ruchi

Hi Ruchi,
You need to use Java Mapping or UDF to create Multipart/Mime

2 levels of MIME attachments in SOAP message

Hello,
I'm not a java specialist, and i want to know a few things before i start something wich eventually turns out impossible to do.
i want to create a SOAP message with one attachment. this attachment must be a multipart/mixed MIME message itself:
-- Part1
soapxml
-- Part1 (1 SOAP attachment = MIME message)
Content-Type: multipart/mixed; boundary:"Part2"
-- Part2
subAttachA
-- Part2
subAttachB
-- Part2
subAttachC
--Part2
--Part1
* first of all: should i use a MimeBodyPart objects for subAttachX and create it with MimeMultiPart.createMimeBodyPart() ?
- that MimeMultiPart i create like this: new MimeMultiPart("mixed") ?
- THIS IS THE MOST IMPORTANT: how do i get this MimeMultiPart into the SOAP attachment part ?
could this work:
//MimeMultipart extends MultiPart + constr: new MimePartDataSource(MultiPart part)
MimePartDataSource mds = new MimePartDataSource(MimeMultiPart multipart);
//MimePartDataSource extends DataSource + constr: DataHandler(DataSource ds)
DataHandler dh = new DataHandler(mds);
//will the following line automatically set: Content-Type: multipart/mixed; boundary:"Part2"
//if not, how can i obtain the boundary (="Part2")
AttachmetPart ap = soapMessage.CreateAttachmetPart(dh);
//will i still be able to set the Content-Id
ap.setContentId("miID");
All help greatly appreciated,
Pieter
