/**
* This class represents an WS-Addressing EndpointReference
* which is a remote reference to a web service endpoint.
* See
* Web Services Addressing 1.0 - Core
* for more information on WS-Addressing EndpointReferences.
*
* This class is immutable as the typical web service developer
* need not be concerned with its contents. The web service
* developer should use this class strictly as a mechanism to
* reference a remote web service endpoint. See the {@link Service} APIs
* that clients can use to that utilize an EndpointReference.
* See the {@link javax.xml.ws.Endpoint}, and
* {@link javax.xml.ws.BindingProvider} APIs on how
* EndpointReferences can be created for published
* endpoints.
*
* Concrete implementations of this class will represent
* an EndpointReference for a particular version of Addressing.
* For example the {@link W3CEndpointReference} is for use
* with W3C Web Services Addressing 1.0 - Core Recommendation.
* If JAX-WS implementors need to support different versions
* of addressing, they should write their own
* EndpointReference subclass for that version.
* This will allow a JAX-WS implementation to create
* a vendor specific EndpointReferences that the
* vendor can use to flag a different version of
* addressing.
*
* Web service developers that wish to pass or return
* EndpointReference in Java methods in an
* SEI should use
* concrete instances of an EndpointReference such
* as the W3CEndpointReference. This way the
* schema mapped from the SEI will be more descriptive of the
* type of endpoint reference being passed.
*
* JAX-WS implementors are expected to extract the XML infoset
* from an EndpointReferece using the
* {@link EndpointReference#writeTo}
* method.
*
* JAXB will bind this class to xs:anyType. If a better binding
* is desired, web services developers should use a concrete
* subclass such as {@link W3CEndpointReference}.
*
* @see W3CEndpointReference
* @see Service
* @since JAX-WS 2.1

* The getPort method returns a proxy. If there

* parameters MUST appear as SOAP headers, indicating them to be

* The parameter serviceEndpointInterface specifies
* the service endpoint interface that is supported by the
* returned proxy.
* The EndpointReference instance specifies the
* endpoint that will be invoked by the returned proxy.
* In the implementation of this method, the JAX-WS
* runtime system takes the responsibility of selecting a protocol
* binding (and a port) and configuring the proxy accordingly from
* the WSDL Metadata from this EndpointReference or from
* annotations on the serviceEndpointInterface. For this method
* to successfully return a proxy, WSDL metadata MUST be available and the
* EndpointReference instance MUST contain an implementation understood
* serviceName metadata.
*
* Because this port is not created from a Service object, handlers
* will not automatically be configured, and the HandlerResolver
* and Executor cannot be get or set for this port. The
* BindingProvider().getBinding().setHandlerChain()
* method can be used to manually configure handlers for this port.
*
*
* @param serviceEndpointInterface Service endpoint interface
* @param features An array of WebServiceFeatures to configure on the
* proxy. Supported features not in the features
* parameter will have their default values.
* @return Object Proxy instance that supports the
* specified service endpoint interface
* @throws WebServiceException
*
* - If there is an error during creation
* of the proxy
*
- If there is any missing WSDL metadata
* as required by this method
*
- If this
*
endpointReference
* is invalid
* - If an illegal
*
serviceEndpointInterface
* is specified
* - If a feature is enabled that is not compatible with
* this port or is unsupported.
