[mule-user] JMS Payload to PDF Email Attachment

Hello

A PDF file is generated by an application and sent to Mule as the payload of a JMS message. Mule must take that payload (which is now the MuleMessage payload?) and send it out as the attachment on an email. From googling I get that I must call message.addAttachment but that's where I'm stuck. That method wants a DataHandler as an argument and that wants a DataSource. My "DataSource" is the message payload. What kind of DataHandler should I use? Once I get the PDF added as an attachment do I need to specify the mime type? If so how?

I'm using Mule EE 2.2.5.

Thanks
Tom

Create a javax.mail.util.ByteArrayDataSource with the PDF's bytes and "application/pdf" as it's content type. Then create a new javax.activation.DataHandler with this data source. That's it, you have an attachment :)

Attached is a transformer to transform a message with as payload bytes from a file and a property "message" as the body for the email to a mulemessage that the email transport can simply send as email.

Just use FileToMuleMessage and then ObjectToMime in smtp:outbound-endpoint.

the mime file has to be put in to your lib dir of the java runtime. This is used by the transformer to set the mimetype for the attachment.

btw this is not working for all versions of the server because there was a bug with the outbound attachments see mule-5118

mime.types

FileToMuleMessage.java

You don't need both stringToEmailTransformer and objectToMimeTransformer, you just need objectToMimeTransformer.

Actually, you're probably hit by: http://www.mulesoft.org/jira/browse/MULE-4601

You can either use the fixed ObjectToMimeTransformer from SVN and patch your Mule, or subclass the existing one, fix it and use it as a custom transformer:

public class FixedObjectToMimeMessage extends ObjectToMimeMessage {

   @Override
   protected BodyPart getBodyPartForAttachment(final DataHandler handler, final String name) throws MessagingException {

   final BodyPart part = new MimeBodyPart();

   part.setDataHandler(handler);
   part.setDescription(name);

   final DataSource source = handler.getDataSource();

   part.setFileName(StringUtils.defaultString(StringUtils.defaultString(source.getName(), handler.getName()), name));

   return part;
   }

}

I'll give that a try but the jira ticket ([MULE-4601|http://www.mulesoft.org/jira/browse/MULE-4601]) says it was fixed in 2.2.2(EE only). I'm running 2.2.5 EE. Shouldn't I have the fix?

I'm doing the exact same thing as you do (generating emails with PDF attached, using Groovy to create the attachment) but with 2.1.1CE, which is why I needed the patch.

But in your case, you have the fix in place as you're using 2.2.5EE, thus your issue is due to some other cause: maybe just remove the useless stringToEmailTransformer?

Cheers,

Mmmh, since you use EE you're best move at this point is to contact support and open a trouble ticket with them.

Hello

There appears to be a similar discussion going on in currently the Developer Forum: [Problem sending pdf as attachment using smtp outbound endpoint|http://forums.mulesoft.org/thread.jspa?messageID=11955#11955]

Okay

I've done some debugging and I think I know what is going on but: 1) I'm not sure I'm right and 2) If I'm right I don't know what to do about it.

When the email:string-to-email-transformer gets invoked the message gets transformed to email format before the email:object-to-mime-transformer gets to see it so the email:object-to-mime-transformer just says:
{code}
DEBUG 2010-10-29 15:35:39,753 [connector.smtp.0.dispatcher.1] org.mule.DefaultMuleMessage: Transformer ObjectToMimeMessage{this=78a974c7, name='objectToMimeTransformer', ignoreBadInput=false, returnClass=class javax.mail.Message, sourceTypes=[class java.lang.String]} doesn't support the source payload: class javax.mail.internet.MimeMessage
{code}
The message gets sent with the payload as the message body and no attachments.

When the email:object-to-mime-transformer alone gets invoked the message gets turned into a multipart/mixed message. In SmtpMessageDispatcher.doDispatch() at the point where sendMailMessage() gets called the message is in the following state:
{code}

The ultimate exception appears to be:

{code}

I notice that the name fields on both of the MimeBodyPart's DataHandlers is a null string. Could this be the issue?

Hello
I believe this is the result of a bug in ObjectToMimeMessage. See the jira ticket for details([MULE-5182|http://www.mulesoft.org/jira/browse/MULE-5182]. There is a workaround in the groovy script below:

import javax.mail.util.ByteArrayDataSource
import javax.activation.DataHandler

String fileName = message.getProperty("originalFilename")

ByteArrayDataSource attachment = new ByteArrayDataSource(message.getPayloadAsBytes(), "application/pdf")

attachment.setName(fileName)

message.addAttachment(fileName, new DataHandler(attachment))
message.setPayload("The original filename is: " + fileName)

return message

The key is the statement "attachment.setName(fileName)" This avoids the problem because it explicitly sets the name on the DataSource. As a result the existing code will work because DataHandler.getName() will no longer return an empty string.

Hi,

I know that this thread is old, but maybe my solution is useful. I'm using mule 3.1. My solution consists of an AbstractMessageTransformer for setting the outboundAttachement and the object-to-mime-Transformer that attaches really the outboundAttachement to the email as mimePart. I defined the following outbound for sending an email with a pdf document as attachement:

<custom-transformer name="orderAttachementTransformer"
class="com.demo.esb.OrderAttachementTransformer">
<spring:property name="templateURL" value="test.pdf" />
</custom-transformer>
......
<smtp:outbound-endpoint host="${smtp.host}"
user="${smtp.user}" password="${smtp.password}" port="${smtp.port}"
from="${smtp.from}" subject="My Message">
<transformer ref="orderAttachementTransformer"/>
<email:object-to-mime-transformer mimeType="*/*" useOutboundAttachments="true"/>
<email:string-to-email-transformer />
</smtp:outbound-endpoint>

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------

My orderAttachementTransformer looks like this:

public class OrderAttachementTransformer extends AbstractMessageTransformer{

private String templateURL;

@Override
public Object transformMessage(MuleMessage message, String outputEncoding)
throws TransformerException {
File f = FileUtils.newFile(templateURL);
InputStream s = null;
try {
s = new FileInputStream(f);
ByteArrayDataSource document = new ByteArrayDataSource(s, "application/pdf");
// TODO: Generate the pdf content here
document.setName("bestellung.pdf");
DataHandler attachement = new DataHandler(document);
message.addOutboundAttachment(outputEncoding, attachement);
} catch (Exception e) {
e.printStackTrace();
}
return message;
}

public String getTemplateURL() {
return templateURL;
}

public void setTemplateURL(final String templateURL) {
this.templateURL = templateURL;
}
}
