Estou tentando ver como funciona o EJB para utiliza-lo em um projeto requerido por meu professor, mas não estou conseguindo fazê-lo funcionar.
Tenho o seguinte código no lado servidor
package ejb;
import javax.ejb.Stateless;
@Stateless (mappedName="HelloBean")
public class HelloBean implements HelloBeanRemote {
@Override
public String sayHello(String name) {
return "Hello " + name;
}
}
e no lado client tenho
package ejb;
import javax.ejb.Remote;
@Remote
public interface HelloBeanRemote {
public String sayHello(String name);
}
package ejbclient;
import ejb.HelloBeanRemote;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class EJBClient {
public static void main(String[] args) {
String message;
try {
InitialContext ctx = new InitialContext();
HelloBeanRemote hello = (HelloBeanRemote) ctx.lookup("HelloBean");
message = hello.sayHello("Test");
} catch (NamingException ex) {
Logger.getLogger(EJBClient.class.getName()).log(Level.SEVERE, null, ex);
message = ex.toString();
} catch (Exception e){
e.printStackTrace();
}
}
}
já dei deploy no server e adicionei o gf-client.jar no client, mas quando executo-o recebo vários erros

Alguem tem ideia de onde estou errando? Minha suspeita é que tenha a ver com o lookup - estou procurando o nome errado ou olhando no lugar errado.
Pode ser algo bem óbvio tendo em vista que não tenho prática nenhuma com EJB, apenas uma base teórica pequena (eu ia ler um livro, mas o prazo de entrega desse trabalho está muito próximo)
