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.
SessionBeanRemote.java
package ejb;
import javax.ejb.Remote;
@Remote
public interface SessionBeanRemote {
String getResult();
String getAddress();
String getCompanyname();
}
|
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.
SessionBeanBean.java
package ejb;
import javax.ejb.Stateless;
@Stateless
public class SessionBeanBean implements SessionBeanRemote {
public String getResult() {
return "Hello World";
}
public String getAddress() {
return "Sec-3,D-16/116,Rohini";
}
public String getCompanyname() {
return "Roseindia.net Pvt.Ltd.";
}
}
|
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.
Main.java
package ejb_remote;
import ejb.SessionBeanRemote;
import javax.ejb.EJB;
public class Main {
@EJB
private static SessionBeanRemote sessionBeanBean;
public static void main(String[] args) {
System.err.println("Accessing Remote Interface using EJB:");
System.out.println("=================================");
System.err.println("Name of the Company is : =" + sessionBeanBean.getCompanyname());
System.err.println("Address of the Company is : =" + sessionBeanBean.getAddress());
System.err.println("Message is : =" + sessionBeanBean.getResult());
System.out.println("=================================");
}
}

Output of the Program
Accessing Remote Interface using EJB:
=================================
Name of the Company is : =Roseindia.net Pvt.Ltd.
Address of the Company is : =Sec-3,D-16/116,Rohini
Message is : =Hello World
