Cannot loadbalance SLSB

[duylt]

I do all thing as cluster doc said. But SLSB cannot loadbalance. I run 2 Jboss AS instance on my destop, only one Jboss AS reply for my call. If I shutdown that Jboss AS, my client side will get error (-> cannot failover)

this is my config:

- jboss.xml :

<jboss>
 .....

 <clustered>True</clustered>
 <cluster-config>
 <partition-name>${jboss.partition.name:DefaultPartition}</partition-name>
 <home-load-balance-policy>
 org.jboss.ha.framework.interfaces.RoundRobin
 </home-load-balance-policy>
 <bean-load-balance-policy>
 org.jboss.ha.framework.interfaces.RoundRobin
 </bean-load-balance-policy>
 </cluster-config>
 ....
</jboss>

- client code :

 Properties props = new Properties();
 props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
 props.setProperty("java.naming.factory.url.pkgs", "jboss.naming:org.jnp.interfaces");
 props.setProperty("jnp.partitionName", m_PartitionName);
 props.setProperty("java.naming.provider.url", m_JNDIServerList);

 InitialContext ctx = new InitialContext(props);
 Object ejbHome = ctx.lookup("ServerBean");
 ServerHome serverHome = (ServerHome) PortableRemoteObject.narrow(ejbHome, ServerHome.class);
 Server server = serverHome.create();

 while(true){
 server.doSomething();
 thread.sleep(2000);
 }

Please help me to resolve this problem
