Yesterday saw the publication of a developerWorks article describing the SRRetrieveITService and SRRetrieveEntity WebSphere Message Broker nodes provided in IA9L SupportPac for integration with WebSphere Service Registry and Repository. The first of these nodes retrieves a service endpoint based on a specified port type. The example shows how this can be used with the HTTP input node to dynamically locate and invoke a service. The second node can be used to retrieve the metadata for an arbitrary entity stored in the Registry and Repository. This could be used, for example, to retrieve policy data relating to the service to be invoked.
