Hi Nishant,
ClassCastException may occur due to several reasons.Check the following:
- All the required jar files are available.
- The correct jar files are available while client call and during deployment.This is the problem with Oracle products not sure about IBM though!
- The Home Object has been published properly in the JNDI namespace.
Most likely the lookup is not able to find the correct HomeObject.This hints to the fact that deployment may not have been correct.Note it may not show errors while deployment but still as I have mentioned in 2, there may be version conflicts.Do confirm that this is not a problem before trying anything different.
Good luck,

Hi!
Thanks for your co-operation.
ok i will tell step by step what i did.
following is my Remote interface
package venus.scc.ejb.stateless.session.bean.nishant;
import java.rmi.RemoteException;
import javax.ejb.EJBObject;
public interface Nishant extends EJBObject
{
public abstract
String getMessage() throws RemoteException;
}
my home interface
package venus.scc.ejb.stateless.session.bean.nishant;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
public interface NishantHome extends EJBHome
{
public abstract Nishant create() throws RemoteException, CreateException;
}
bean class
package venus.scc.ejb.stateless.session.bean.nishant;
import java.rmi.RemoteException;
import java.util.ListResourceBundle;
import java.util.ResourceBundle;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
public class NishantBean implements SessionBean
{
public NishantBean() { }
public void ejbActivate() throws RemoteException { }
public void ejbCreate() { }
public void ejbPassivate() throws RemoteException { }
public void ejbRemove() throws RemoteException { String msgs = null; }
public String getMessage() throws RemoteException {
return "Nishant";
}
public void setSessionContext(SessionContext sessioncontext) throws RemoteException { }
}
i keep them inpacakege structure like "venus.scc.ejb.stateless.session.bean.nishant" where venus folder is at deployableEJBs,then i run th following script
jar cfv nishantkijar.jar venus/scc/ejb/stateless/session/bean/nishant/*.class
then i opened this jar file with jetace and put the name of bean as venus.scc.ejb.stateless.session.bean.nishant.NishantBean
then i save the saved the resulting jar file in deployed using admin console it deployed sucessfully and i started it,
at classpath all deployed jar files are present.
please tell me where is the mistake
