Hello ,
I am using JBoss [Zion] 4.0.3RC1.Here is the code of my session bean
Home Interface
------------------
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
public interface AdviceHome extends EJBHome{
public AdviceComponent create() throws RemoteException,CreateException;
}
Component Interface
-------------------------
package com.fritolay;
import java.rmi.RemoteException;
import javax.ejb.EJBObject;
public interface AdviceComponent extends EJBObject{
public String getAdvice() throws RemoteException;
}
Bean class
--------------
package com.fritolay;
import java.rmi.RemoteException;
import javax.ejb.EJBException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
public class AdviceImpl implements SessionBean{
public void ejbActivate() throws EJBException, RemoteException {
// TODO Auto-generated method stub

RemoteException {
// TODO Auto-generated method stub
}
public void ejbCreate(){
System.out.println("ejbcreate method called...");
}
public String getAdvice(){
return "No Advice Temporirly";
}
}
Client code
----------------
package com.fritolay;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
public class AdviceClient {
public static void main(String[] args) {
InitialContext context = null;
try {
java.util.Hashtable JNDIParm = new java.util.Hashtable();
JNDIParm.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
JNDIParm.put(Context.URL_PKG_PREFIXES,
"org.jnp.interfaces");
JNDIParm.put(Context.PROVIDER_URL, "localhost:1099" );
context = new InitialContext(JNDIParm);
if(context==null){
System.out.println("Context is Null");
}
else
{
System.out.println("Context is Not Null");
}
Object o=context.lookup("kamini");
AdviceHome
hec=(AdviceHome)PortableRemoteObject.narrow(context.lookup("kamini"),AdviceHome.class);
}
catch(Exception e){
e.printStackTrace();
}
}
}
