[jboss-user] [Clustering/JBoss] - Re: RoundRobin, new cluster member & SFSB == NPE

[ben.wang@jboss.com]

No, I can't reproduce from my system. I have tried both RoundRobin and FirstAvailable. They failover just fine. I use two node cluster to restart one.

Here is my bean code snippet:

  | @Stateful(name="GangDispute")
  | @Clustered(loadBalancePolicy= org.jboss.ha.framework.interfaces.FirstAvailable.class)
  | //@Clustered
  | @Remote(GangDispute.class)
  | public class GangDisputeBean implements java.io.Serializable, GangDispute
  | {
  |    private long arrestedGuys = 0;
  | 
  |         public long newGuysArrested(long newArrests)
  |    {
  |       arrestedGuys+=newArrests;
  |       System.out.println("Total arrested guys: " + arrestedGuys + "( +" + newArrests + " arrests)");
  |       return arrestedGuys;
  |    }
  | 
  |         public long getNbArrestedGuys ()
  |    {
  |       return arrestedGuys;
  |    }
  | 
and client

  |    Client () throws Exception
  |    {
  |       //Get JNDI context
  |       Context naming = new InitialContext ();
  |       ClassLoader loader = Thread.currentThread().getContextClassLoader();
  |       Enumeration rsrcs = loader.getResources("jndi.properties");
  |       while( rsrcs.hasMoreElements() )
  |       {
  |          System.out.println(rsrcs.nextElement());
  |       }
  |       System.out.println("JNDI.env: "+naming.getEnvironment());
  |       System.out.println("Looking up GangDispute/remote");
  |       //Look up the Remote
  |       gd = (GangDispute)naming.lookup ("GangDispute/remote");
  |    }
  | 
  |    public void test ()
  |    {
  | 
  |       try
  |       {
  |          while (true)
  |          {
  |             long total = gd.newGuysArrested (1);
  |             System.out.println("Total number of arrested guys: " + total);
  | 
  |             try
  |             {
  |                synchronized (this)
  |                {
  |                   this.wait (1000);
  | 
  | ...
  | 
and jndi.prperties:

  | java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
  | java.naming.provider.url=jnp://localhost:1100
  | java.naming.factory.url.pkgs=org.jboss.naming
  | 

I am now using exactly 4.0.5.GA as well. How do you run yours?
