The relation between a BPEL process and different partner links can be stored in a deployment file. This file contains a description for every partner link mention in the process. The descriptor file simplifies deployment. Entering the URL of this file through the web administration interface will download and register all sources needed for the process compilation.

The format of the deployment file is as follows:

xml:id="[process id]" src="[URI of the file containing BPEL script]">
                        <partnerLinkBinding name="[name of the partner]">
                            <property name="wsdlLocation">[URI of the WSDL for the partner]</property>
                        ... more partnerLinkBinding may follow ...
