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