This figure shows the relationship between the payload data of a native format message and the D3L file magic value message header attribute.

The payload data of a native format message takes the following format:

POST /oai/servlet/transportServlet HTTP/1.1

Content-Type: application/x-www-form-urlencoded

Host: acme.com:8888

Content-Length: 28

D3L-Header: price

"*UPDATE_PRICE* 2468 |199.99|"

The D3L file magic value message header attribute can take the following format:

<message name="modify" object="Employee" type="modifyCommand" magic="*UPDATE_PRICE">

One arrow shows the relationship between the two pieces of code:

• An arrow points from the first n bytes of payload data in the native format message (*UPDATE_PRICE) to the value *UPDATE_PRICE in the magic attribute of the message element of the D3L file.
