Hi all,
Now i'm Learning EJB, i have proplem but I can't fix, can you help me, thanks very much. My program have EJB is

public class SessionBean implements ISessionBeanRemote {

public String GetAddress(String param) {
return "Agribank";

public String GetName(String param) {
return "Hoang Phuong Thuc";

and Interface :
public interface ISessionBeanRemote {

String GetAddress(String param);

String GetName(String param);


I uses function lookup:
Properties env = new Properties();

// Definir las propiededes y ubicacion de busqueda de Nombres JNDI.
env.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
env.setProperty("java.naming.provider.url", "localhost:1099");
env.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");

Context context=new InitialContext(env);

String name="SessionBean/remote";
ISessionBeanRemote sessionBeanBean=(ISessionBeanRemote)context.lookup(name);

When I write in Main function is OK but not OK in servlet, and have Error is:

java.lang.ClassNotFoundException: agribank.ISessionBeanRemote (no security manager: RMI class loader disabled)

I'm not a pro at this so I did some googling and I think this tutorial might help you. I think this is happening because of some security reasons...
