Answer 1

here are the 3 classes.
package com.brainysoftware.ejb;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
public interface Adder extends EJBObject {
public int add(int a, int b) throws RemoteException;
package com.brainysoftware.ejb;
import java.rmi.RemoteException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
public class AdderBean implements SessionBean {
public int add(int a, int b) {
System.out.println("from AdderBean");
return (a + b);
public void ejbCreate() {
public void ejbRemove() {
public void ejbActivate() {
public void ejbPassivate() {
public void setSessionContext(SessionContext sc) {
package com.brainysoftware.ejb;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
public interface AdderHome extends EJBHome {
Adder create() throws RemoteException, CreateException;
}and has been made adder.jar using
E:\ejb\classes>jar cfv adder.jar com/brainysoftware/ejb/* META-INF/ejb-jar.xml
then drag this adder.jar and placed it into Jboss deploy directory.
restarted Jboss and got the error mesaage

lt/tmp/deploy/tmp63365adder.jar restart will delete it
