Service Implementation Bean
A Service Implementation Bean (SIB), is a term used in Java Platform, Enterprise Edition, for a Java object implementing a web service. It can be either a POJO or a Stateless Session EJB.

Java Platform, Enterprise Edition
Jakarta EE, formerly Java Platform, Enterprise Edition (Java EE) and Java 2 Platform, Enterprise Edition (J2EE), is a set of specifications, extending Java SE with specifications for enterprise features such as distributed computing and web services. Jakarta EE applications are run on reference runtimes, that can be microservices or application servers, which handle transactions, security, scalability, concurrency and management of the components it is deploying. Jakarta EE is defined by its specification. The specification defines APIs (application programming interface) and their interactions. As with other Java Community Process specifications, providers must meet certain conformance requirements in order to declare their products as ''Jakarta EE compliant''. Examples of contexts in which Jakarta EE referencing runtimes are used are: e-commerce, accounting, banking information systems. History The platform was known as ''Java 2 Platform, Enterprise Edition'' or ''J2EE'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stateless Session Bean
Jakarta Enterprise Beans (EJB; formerly Enterprise JavaBeans) is one of several Java APIs for modular construction of enterprise software. EJB is a server-side software component that encapsulates business logic of an application. An EJB web container provides a runtime environment for web related software components, including computer security, Java servlet lifecycle management, transaction processing, and other web services. The EJB specification is a subset of the Java EE specification. Specification The EJB specification was originally developed in 1997 by IBM and later adopted by Sun Microsystems (EJB 1.0 and 1.1) in 1999 and enhanced under the Java Community Process aJSR 19(EJB 2.0)JSR 153(EJB 2.1)JSR 220(EJB 3.0)JSR 318(EJB 3.1) anJSR 345(EJB 3.2). The EJB specification provides a standard way to implement the server-side (also called " back-end") 'business' software typically found in enterprise applications (as opposed to 'front-end' user interface software).

Interface (Java)
An interface in the Java programming language is an abstract type that is used to describe a behavior that classes must implement. They are similar to protocols. Interfaces are declared using the interface keyword, and may only contain method signature and constant declarations (variable declarations that are declared to be both static and final). All methods of an Interface do not contain implementation (method bodies) as of all versions below Java 8. Starting with Java 8, default and static methods may have implementation in the interface definition. Then, in Java 9, private and private static methods were added. At present, a Java interface can have up to six different types. Interfaces cannot be instantiated, but rather are implemented. A class that implements an interface must implement all of the non-default methods described in the interface, or be an abstract class. Object references in Java may be specified to be of an interface type; in each case, they must either be nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Endpoint Interface
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. In Open API terms the endpoints are resources that the API exposes. The old (2004) term "end point" received also a glossary definition: : ''An association between a binding and a network address, specified by a URI, that may be used to communicate with an instance of a service. An end point indicates a specific location for accessing a service using a specific protocol and data format. SD Reqs' SOAP and Java context A SOAP-based web service can be implemented as a single Java class. An endpoint interface, also known as a service e ...
