The program given below describes the way of creating a remote interface in EJB. The meaning of Remote interface in terms of Ejb is the java source file which contain the bean implementation logic. These are very much similar to the RMI Remote interface and provides the business specific functionality of an EJB. Here we have created the Remote interface named SessionBeanRemote.java
@Remote:- This is the annotation which is used to declare the interface as Remote.
String getResult(); String getAddress();String getCompanyname():-These
are the methods which are to be defined inside the bean.
SessionBeanBean.java:- This is the session bean
in which we will declared all the methods of the Remote interface. This bean is
used for controlling the business process and filling the gaps between the data
of the entity beans. Here
@Stateless is the annotation which denotes the bean is of session type.
Main.java:- This is the client application from which we can access all the methods of the session bean.
@EJB:-This is the annotation that configure the EJB values for a field or a method. This annotation is a Resource annotation and is used where it is known that the resultant is an EJB interface.
