Retrieving MailMessage bodies as DataHandler objects

Hi there,

Supposing that I receive an Exchange using Camel Mail and I want to see
whether the body is of the required MIME type; is it valid to do this:

  // See if our exchange body contains the calendar object.
  DataHandler bodyDataHandler = exchange.getIn().getBody(
  		DataHandler.class);
  if (bodyDataHandler != null) {
    ...
  }

I know that I can retrieve attachments as DataHandlers, but am I able to do
so for the body itself? The documentation implies that the body is coerced
to a string...

I have already incorporated the above code in my application and I'm waiting
for someone to send the type of message that may also answer this post.
However it'll be several hours before I know.

Thanks!

Kind regards,
Christopher

Thanks Claus. I'm now trying out the following and just waiting for another
message to come through:


  // See if our exchange body contains the calendar object.
  javax.mail.Message mailMessage = exchange.getIn(MailMessage.class)
    .getMessage();
  if (logger.isDebugEnabled()) {
    logger.debug("Message received: " + mailMessage);
  }
  try {
    DataHandler bodyDataHandler = mailMessage.getDataHandler();
    if (bodyDataHandler != null) {
      addCalendarDataToCalendars(calendars, bodyDataHandler);
    }
  } catch (MessagingException e) {
    logger.error(e);
  }

Hi

You can get access to the underlying javax.mail.Message
https://svn.apache.org/repos/asf/camel/trunk/components/camel-mail/src/main/java/org/apache/camel/component/mail/MailMessage.java

javax.mail.Message mailMessage = exchange.getIn(MailMessage.class).getMessge();

And maybe there is a type converter for that as well. I cant remember
javax.mail.Message mailMessage = exchage.getIn().getBody(javax.mail.Message);

Thanks Willem - I know about the attachments. My case is where I'm dealing
with a single part message and its not text content i.e. its text/calendar.

Hi,

Camel Message has getAttachements() method which can help you get the 
DataHandlers.
You can find the unit test of camel-mail here[1]
