Endpoint interface
Encyclopedia
An endpoint interface, also known as a service endpoint interface (SEI), is a term used in Java Platform, Enterprise Edition
when exposing Enterprise JavaBean
s as a Web service
(see also Service Implementation Bean
(SIB)). It is annotated with
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.
Java Platform, Enterprise Edition

@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.
