[jboss-user] [EJB 3.0] - Cluster Stateful EJB 3.0 problems

[viniciuscarvalho]

Hello there! I'm trying to get a SFSB in a jboss 4.2.0 cluster. It's a simple example. A bean that increments a value. My bean's interface and implementation:


  | @Remote
  | public interface Contador {
  | 
  | 	public abstract int increase();
  | 
  | 	public abstract int decrease();
  | 
  | }
  | 
  | @Stateful
  | public class ContadorBean implements Contador {
  | 	private int count;
  | 	
  | 	public int increase(){
  | 		count++;
  | 		System.out.println("Contador no valor: " + count);
  | 		return count;
  | 	}
  | 	
  | 	public int decrease(){
  | 		count--;
  | 		System.out.println("Contador no valor: " + count);
  | 		return count;
  | 	}
  | 	
  | 	@Remove
  | 	public void destroy(){
  | 		
  | 	}
  | }
  | 
  | jndi properties for the client:
  | java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
  | java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
  | java.naming.provider.url=jnp://192.168.0.169:1100
  | 
  | jboss.xml:
  | <jboss>
  |   <enterprise-beans>
  |    <session>
  |       <ejb-name>ContadorBean</ejb-name>
  |       <clustered>True</clustered>
  |     </session>
  |   </enterprise-beans>
  | </jboss>
  | 
  | 

Well, I startup 2 instances, deploy the package on the farm directory. and start the client. Things are just ok :) 
So I decide to shutdown one of the nodes...
and I get this exception:
