In the
Web service context the term endpoint received a formal definition with the W3C recommendation "
WSDL 2.0" of 2007,
: ''Defines the address or connection point to a Web service. It is typically represented by a simple HTTP URL string''
The term "endpoint interface" is more specific about "how to implement the endpoint", for example by an OpenAPI specification or by WSDL specification. Typical endpoints can be expressed by
URI Templates.

(SIB)). It is annotated with
@WebService and is a component interface, which declares all the abstract methods that are exposed to the client. As it extends the
java.rmi.Remote interface, all methods must throw the
RemoteException. A Web service client accesses a
stateless session bean through the bean's Web service endpoint interface. Like a
remote interface, a Web service endpoint interface defines the business methods of the bean.
In contrast to a remote interface, a Web service endpoint interface is not accompanied by a
home interface, which defines the bean's life-cycle methods. The only methods of the bean that may be invoked by a Web service client are the business methods that are defined in the Web service endpoint interface.
The methods of an endpoint interface for a Web service are implemented in a session bean class that is stateless.
