Publishing a Web Service 
You can publish Web services developed in ABAP in Services Registry. At the core of Services Registry is an open standard UDDI v3.0 conformant registry. Located centrally within a SOA landscape, Services Registry contains information about services provided in that landscape, with references to the services’ relevant WSDL metadata and to the locations of the callable service endpoints. The registered services are classified using semantic-rich classification systems to enable browsing of services by classification.
Note
Services Registry is present only on systems with AS Java.
Features
Services can be published in Services Registry in the following ways:
You can publish the tModel of the service in question from the Object Navigator.
For more information, see Editing a Service Definition.
Service definitions and service end points can be published in the Services Registry from the ABAP Application Server.
For more information, see Publishing Services.
From the ABAP back end, you can also use transactions WSPUBLISH and WSCLASS to publish and classify services. For more information, see Classifying a Service and Publishing a Service.

In Services Registry, you can check whether the service has been correctly published. For more information about how to search and browse service definitions, see the documentation of Services Registry.
