Handling attachments in XI

Question

Hi All,
I am working on a scenario where in I recieve the Payload from a web service.The payload consists of 2 parts one is the xml document and the second is the attachment (image,PDF,..).When I monitor the messages in sxmb_moni I find 2 payloads as shown below.
Payloads
             attachment-1 ( image/jpeg )
              MainDocument ( text/xml;charset=utf-8 )
I have a file server on the reciever side and I want 2 files to be created on the target side i.e., one the xml file and the second the attachment.
Can anyone help me how can I handle the 2 payloads either in mapping or during configuration.
Is it possible to handle the attachments in mapping(XSLT or Java) and how?
Thanks in advance.

Hi Vikram,
I believe you can achieve this requirement by using Java mapping and Multi-Mapping techniques.
1. Create 2 target Message Types a] Message type for Original payload (for Eg. MsgType1) b] Message type for Binary Attachment data (for Eg. MsgType2)
2. In Interface mapping include 2 target messages MsgType1 and MsgType2
3. Make MsgType1 occurrence as 1 and MsgType2 occurrence as 0 to Unbounded
4. Write a Java mapping to generate the Multi-Mapping payload with one Message for MsgType1 and 0 or more messages for MsgType2.
5. Java mapping program has to utilize Message interface functions getAttachmentIterator()
from com.sap.engine.interfaces.messaging.api.Message
and generate the Binary payload for MsgType2.
6. Configure one file adapter for main payload (MsgType2) and one more for Binary payload (MsgType2)
Hope this helps.
