JAX-WS 2.0 Beta
J2SE Endpoints

Last Modified: 12/08/05

Web Service endpoints can be created and published programmatically using javax.xml.ws.Endpoint API. An endpoint consists of a Web Service Implementation object and some configuration information. The implementation hosts the web service endpoint using a light weight http server and clients can access the web service as if the endpoint is deployed in a J2EE container. This means that there is no need to have any J2EE servlet or ejb container to host the endpoint.  The Endpoint API provides a way to configure the endpoint with the necessary binding, metadata(WSDL and schema documents), handlers etc.

Endpoint

An endpoint can be created using any of the following constructors: 
Endpoint.create(implementor)
Endpoint.create(bindingId, implementor)
Endpoint.publish(address, implementor)
Once the Endpoint object is created using the first two constructors, it can be published using Endpoint.publish(). Any published Endpoint can be stopped using Endpoint.stop(). supplychain sample shows creating and publishing an Endpoint.

Endpoint and Properties

An endpoint can be configured to match service name and port name of WSDL using properties. This overwrites implementor object's serviceName, portName from @WebService annotation. The port address for an endpoint is patched only if the corresponding port's service name, and port name in WSDL are matched.

For example:

  Endpoint endpoint = ...
  Map<String, Object> map = new HashMap<String, Object>();
  map.put(Endpoint.WSDL_SERVICE, new QName(...));
  map.put(Endpoint.WSDL_PORT, new QName(...));
  endpoint.setProperties(map);

Endpoint and Binding

Endpoint can be configured for different bindings using binding ids. These binding ids are defined in JAX-WS API and endpoint can be configured by specifying @BindingType annotation or using binding id in the Endpoint() constructors. The parameter in constructor overwrites binding defined by @BindingType annotation. If the binding is not specified using @BindingType or using a parameter in Endpoint() constructor, the default binding is SOAP1.1/HTTP. Binding object is used to configure MTOM, handler chain etc. SOAP binding object is used to configure SOAP binding specifics like roles.

For example:

  The following configures the endpoint for XML/HTTP binding.

  Endpoint endpoint = Endpoint.create(HTTPBinding.HTTP_BINDING, implementor);

For example:

  // setting MTOM
  SOAPBinding binding = (SOAPBinding)endpoint.getBinding();
  binding.setMTOMEnabled((true);

  // setting SOAP binding roles
  binding.setRoles(...);

  // setting handler chain
  binding.setHandlerChain(...);

Endpoint and metadata

When the service endpoint is created using existing java classes, the implementation dynamically generates and publishes WSDL and schema documents. But when the service endpoint is created using existing WSDL documents, the same WSDL documents can be used for publishing using metadata facility. When a Source object is created, set systemid always and make sure the imports are resolvable w.r.t systemids.

For example:
   // metadata processing for WSDL, schema files
   List <File> metadataFile = ...
   List<Source> metadata = new ArrayList<Source>();
   for(File file : metadataFile) {
       Source source = new StreamSource(new FileInputStream(file));
       source.setSystemId(file.toURL().toExternalForm());
       metadata.add(source);
   }
   endpoint.setMetadata(metadata);
