Endpoint References and WS-Addressing Considerations

At deployment time, you need to specify the location information for each partner link endpoint reference. Also, you can assign an endpoint reference dynamically, detailed in the Copy Operation Dynamic Endpoint Reference Example.

One of the main protocols to specify location information for an endpoint reference is based on the Web Services Addressing (WS-Addressing) specification.

The WS-Addressing specification standardizes the format for referencing a Web service allowing you to create uniquely identified Web services and Web service instances that are not bound to a specific transport mechanism, such as HTTP. Using WS-Addressing, the endpoint information is added to the header of a SOAP request and not to the URL specified in the SOAP body.

Having endpoint reference information in a SOAP header means that you can do the following:

Specify Web service instance IDs

Select Reply To
and Fault To
addressees

Select From
endpoint references in the case where an acknowledgement needs to be sent back to the sender

Note that in Process Server, you can specify other mechanisms besides SOAP over HTTP. For details, see

Custom Service Interactions

The basic WS-Addressing syntax is as follows:

<wsa:EndpointReference>
  <wsa:Address>anyURI</wsa:Address>
  <wsa:ServiceName PortName="portname">Service QName
    </wsa:ServiceName>
</wsa:EndpointReference>

where:

Address

is a mandatory element that identifies an endpoint. It can be a network address or a logical address.

ServiceName

is the qualified name, or QName, for the service being invoked. This service must be defined in a WSDL file that is deployed with the process or one that is available in Process Server's resource catalog.

PortName

identifies the service port being invoked. Note that you can specify a port binding of SOAP 1.1 or SOAP 1.2.

You can add credential details to the endpoint reference, described in

The following versions of the WS-Addressing specification are supported:

This is the default version that the PDD uses. For changing the default, see
