// this is remote intterface class
public interface remote extends javax.ejb.EJBObject{
public String show() throws java.rmi.RemoteException;
//home interface
import javax.ejb.*;
import java.rmi.*;
public interface homeinter extends EJBHome{
remote create()throws CreateException,RemoteException;
//bean
import javax.ejb.SessionBean;
import javax.ejb.EJBException;
import java.rmi.RemoteException;
import javax.ejb.SessionContext;
public class bean implements SessionBean {
SessionContext sct;
public String show() throws RemoteException {
return " this is from bean";
public void ejbActivate(){}
public void ejbPassivate(){}

this.sct=set;
// client
import javax.ejb.*;
import javax.rmi.*;
import javax.naming.*;
import java.rmi.*;
public class client {
public static void main(String[] args) {
try{
InitialContext ic= new InitialContext();
Object obj= ic.lookup("MySecond");
homeinter h=(homeinter)PortableRemoteObject.narrow(obj,homeinter.class);
remote r=h.create();
System.out.println("the return value is" + r.show());
}catch(Exception e){
e.printStackTrace();
in the DOS prompt i tried to run the programme like
set CPATH=.;c:\j2ee\lib\j2ee.jar;secondClient.jar
java -Dorg.omg.CORBA.ORBInitialHost=lacalhost -classpath %CPATH% client
then i had the following error mesage
C:\ejb>set CPATH=.;c:\j2ee\lib\j2ee.jar;secondClient.jar

Answer 1

1. which app server u r using ? R u using RI ?
2. what is this secondclient.jar ?
3. Have u added server specific jar containing implementation of IntialConrtextFactory in the classpath of client?
4. If using RI, then I suppose u will have to set "Support Client Choice" (Possibly) to true, then generate client.jar.
5. Which IDE u r using (If any) ?
6. Are u sure that ur jar file (containng EJBs) deployed successfully ?
7. Almost every server provides GUI console sort of , u can check whether it was deployed successfuly ?
Pls update
