Implementation of WS-Addressing in CentraSite
CentraSite can import and virtualize WSDLs having WS-Addressing annotations. For the virtualized services, the annotations are kept in the WSDL because they do not contain relevant information about the native service endpoint.
The following WS-Addressing headers can be included in a WSDL:
<wsam:UsingAddressing wsdl:required="true" />Explicit
wsam:Action attributes for operation input/output elements. For example:
wsam:Action="http://greath.example.com/2004/wsdl/resSvc/opCheckAvailability"
Default actions for inputs and outputs (for backwards compatibility with WSDL 1.1). The following pattern is used to construct a default action for inputs and outputs. The general form of an action Internationalized Resource Identifier (IRI) is as follows:
wsam:Action="[target namespace][delimiter][port type name][delimiter][input|output name]"
Endpoint references, such as:
<wsa10:EndpointReference> <wsa10:Address>[url]</wsa10:Address> </Identity> </wsa10:EndpointReference> What happens to these WS-Addressing headers?
For a native service (created through import WSDL), the WSDL remains as is.
For a virtual service:
The WS-Policy attachment block (containing the
UsingAdressing element) is removed.
The
wsam:Action attributes remain on the operations.
The endpoint references are removed because they are replaced by
Mediator's endpoint information.
