Setting up publishing for Experience Manager
To be able to publish to an Experience Manager-enabled Content Delivery environment, the Preview Service must have been set up on the Content Delivery side, and its Capability must have been registered with its Discovery Service. To find out if Experience Manager is set up properly, access http://SERVER:PORT/discovery-service/discovery.svc/Environment/PreviewWebServiceCapability, where SERVER:PORT identifies the server and port on which the Discovery Service runs. An empty return value means that this environment has no Preview Service set up.
