[jboss-user] [EJB 3.0] - Stateful bean via RMI

[hipa]

I can't get access to stateful bean, but can to stateless one. Why?

  | package org.test.ejb;
  | 
  | public interface StatelessRemote
  | {
  |     public void test();
  | }
  | 


  | package org.test.ejb;
  | 
  | public interface StatefulRemote
  | {
  |     public void test();
  |     public void destroy();
  | }
  | 


  | package org.test.ejb;
  | 
  | import javax.ejb.Stateless;
  | import javax.ejb.Remote;
  | 
  | import org.test.ejb.StatelessRemote;
  | 
  | @Stateless
  | @Remote(StatelessRemote.class)
  | public class StatelessBean
  | implements StatelessRemote
  | {
  |     public void test()
  |     {
  |         System.out.println("test stateless");
  |     }
  | }
  | 


  | package org.test.ejb;
  | 
  | import javax.ejb.Stateful;
  | import javax.ejb.Remote;
  | import javax.ejb.Remove;
  | 
  | import org.test.ejb.StatefulRemote;
  | 
  | @Stateful
  | @Remote(StatefulRemote.class)
  | public class StatefulBean
  | implements StatefulRemote
  | {
  |     public void test()
  |     {
  |         System.out.println("test stateful");
  |     }
  | 
  |     @Remove
  |     public void destroy()
  |     {
  |         System.out.println("Destroy");
  |     }
  | }
  | 

Client code

  | ...
  | InitialContext context = new InitialContext(jndiProps);
  | NamingEnumeration en = context.list("java:/ejb_test");
  | while (en.hasMore())
  | {
  |     System.out.println(en.next());
  | }
  | 
  | Object stateless = context.lookup("StatelessBean/remote");
  | System.out.println("Bean received " + stateless);
  | 
  | Object stateful = context.lookup("StatefulBean/remote");  // 109
  | System.out.println("Bean received " + stateful);
  | ...
  |
