Send PDF in JavaMail

[Dave Wingate]

I have little experience with javamail and would really appreciate any help you could offer on this error. I'm trying to send a pdf (in memory) as an attachment to an email.

So far I've got:

 msg = createMessage();
[snip]            
            MimeBodyPart messageBodyPart = new MimeBodyPart();
 
            //fill message
            messageBodyPart.setText(msgText);
 
            Multipart multipart = new MimeMultipart();
            multipart.addBodyPart(messageBodyPart);
 
            // Part two is attachment
            if ((attachmentStreamToFileNameMap != null) && !attachmentStreamToFileNameMap.isEmpty())
            {
                for (Iterator iter = attachmentStreamToFileNameMap.keySet().iterator(); iter.hasNext()  :wink:  
                {
                    InputStream attach = (InputStream) iter.next();
                    
messageBodyPart = new MimeBodyPart();
messageBodyPart.setDataHandler(
  new DataHandler(new InputStreamDataSource(attach,
  (String) attachmentStreamToFileNameMap.get(attach), "application.pdf")));
 
                    messageBodyPart.setFileName((String) attachmentStreamToFileNameMap.get(attach));
                    multipart.addBodyPart(messageBodyPart);
                }
            }
 
            // Put parts in message
            msg.setContent(multipart); 

And this helper class:

 
class InputStreamDataSource implements DataSource {
 
InputStream content;
String filename;
String contentType;
 
public InputStreamDataSource(InputStream content, String filename, String
contentType) {
this.content = content;
this.filename = filename;
this.contentType = contentType;
}
 
public InputStream getInputStream() {
return content;
}
 
public OutputStream getOutputStream() {
return new java.io.ByteArrayOutputStream();
}
 
public String getContentType() {
return contentType;
}
 
public String getName() {
return filename;
}
 

When run, I'm getting the following exception:

SMTPMailSender |javax.mail.internet.ParseException

Just before sending the message, the headers are:

Can anybody tell me what I've done wrong here?

I also noticed that the DataHandler has objectMimeType set to "multipart/mixed;
boundary="----=_Part_1_2073066384.1121471029718""

Can this be right? Is this the problem?

You have to write your implementation of DataSource so that it returns a new instance of the InputStream every time getInputStream() is called. You have to read it into a buffer in order to do this. Here's my implementation of InputStreamDataSource which I've tested (it works )

private class InputStreamDataSource implements DataSource {
 
        private String name;
        private String contentType;
        private ByteArrayOutputStream baos;
        
        InputStreamDataSource(String name, String contentType, InputStream inputStream) throws IOException {
            this.name = name;
            this.contentType = contentType;
            
            baos = new ByteArrayOutputStream();
            
            int read;
            byte[] buff = new byte[256];
            while((read = inputStream.read(buff)) != -1) {
                baos.write(buff, 0, read);
            }
        }
        
        public String getContentType() {
            return contentType;
        }
 
        public InputStream getInputStream() throws IOException {
            return new ByteArrayInputStream(baos.toByteArray());
        }
 
        public String getName() {
            return name;
        }
 
        public OutputStream getOutputStream() throws IOException {
            throw new IOException("Cannot write to this read-only resource");
        }
    }

Hello all,

Has anyone worked on SearchTerm?

Brilliant. Buffering the inputstream worked for me as well. Thanks for your help. I've been beating my head against the monitor for quite a while on this one.

Great work Dave..
but still I want to know what is the advantage of the following Buffering code.

 
int read;            byte[] buff = new byte[256];            while((read = inputStream.read(buff)) != -1) {                baos.write(buff, 0, read);            }

I am trying to implement something similar to this. Does this work for xls files and doc files or does it mess the format.
