Implementing the Web Service using SOAP

Service: Submit a Purchase Order (PO)
- The client creates a SOAP document that contains a PO instance document (which conforms to the PO schema that Parts Depot has created)

<?xml version="1.0"?>

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

<soap:Body>

<p:PurchaseOrder xmlns:p="http://www.parts-depot.com">

...

</p:PurchaseOrder>

</soap:Body>

</soap:Envelope>

Once again, the client will HTTP POST this document to the SOAP server at:

http://www.parts-depot.com/soap/servlet/messagerouter

Note that this is the same URL as was used with the other two services.

The SOAP server peeks into this document to determine what procedure to invoke.
