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.
