Extract attachments from Outlook.msg files using ColdFusion

Question

I am creating a system where intranet users are allowed to drag and drop files into divour ColdFusion website, which after some verification will automatically upload them to the file server. One of my requirements: when the downloaded file is a file .msg(Outlook Email), extract any files that are attachments to this email and download them separately. This is possible using a org.apache.poi.hsmf.MAPIMessageJava object . Following the code below, I can see how each of the listed objects is attached. Then I can get their names and extensions and save them to the local file system.

However, this does not work if the attachment is a different file .msg. When I call getEmbeddedAttachmentObject()in the attached file .msg, it returns an object that contains only "undefined". Files .msgreturn a binary object that I can then pass to the FileWrite()ColdFusion function . Further examination of the object MAPIMessageshows that it has a method write(), but after calling it, I get an error message:

Note. Recording on this file is not yet supported.

This is confirmed by the documentation at http://poi.apache.org .

To summarize, I can write each attachment of an electronic message to the file system without problems if the attachment is not another electronic message. Am I lucky or is there another way to do this?

<cfscript>
  // Load test .msg into MAPIMessage object
  MAPIMessage = createObject("java", "org.apache.poi.hsmf.MAPIMessage");
  message = MAPIMessage.init('C:\Test\Test Email 1 Attachment.msg');

  // Get array of attached files
  attachments = message.getAttachmentFiles();

  // If attachments were found
  if(arrayLen(attachments) > 0) {

    // Loop over each attachment
    for (i=1; i LTE arrayLen(attachments); i++) {

      // Dump the current attachment object
      writeDump( attachments[i] );

      // Get current attachment binary data
      local.data=attachments[i].getEmbeddedAttachmentObject();

      // Dump binary data
      writeDump( local.data );

      // Get attachment filename and extension
      attachmentFileName = attachments[i].attachLongFileName.toString();
      attachmentExtension = attachments[i].attachExtension.toString();

      // Dump filename and extension
      writeDump( attachmentFileName );
      writeDump( attachmentExtension );

      // Write attachment to local file system     
FileWrite("#expandPath('/')##attachments[i].attachLongFileName.toString()#", local.data);

   }
  }
