Enterprise Java Bean Example\r
Stateless Session Bean\r
\r
In this video we will create servlet and Java Bean\r
Will also create EJB stateless Session Bean.\r
\r
Enterprise JavaBeans (EJB) is a managed, server software for modular construction of enterprise software, and one of several Java APIs.\r
EJB is a server-side software component that encapsulates the business logic of an application.\r
The EJB specification is a subset of the Java EE specification.\r
An EJB web container provides a runtime environment for web related software components, including computer security,Java servlet lifecycle management, transion processing, and other web services.\r
\r
\r
A stateless session bean does not maintain a conversational state with the client.\r
When a client invokes the methods of a stateless bean, the beans instance variables may contain a state specific to that client but only for the duration of the invocation.\r
When the method is finished, the client-specific state should not be retained.\r
Clients may, however, change the state of instance variables in pooled stateless beans, and this state is held over to the next invocation of the pooled stateless bean.\r
Except during method invocation, all instances of a stateless bean are equivalent, allowing the EJB container to assign an instance to any client.\r
That is, the state of a stateless session bean should apply across all clients.\r
