Hi All,

I have 2 jboss nodes configured in cluster which is for QA environment.

When my application try to lookup the Queue destination on HA-JNDI port which is 1100 i get following exception on one node but at the same time it picks the Queue from other node

2007-09-21 11:17:42,293 DEBUG [org.jnp.interfaces.NamingContext] Failed to connect to null:1100
javax.naming.CommunicationException: Failed to connect to server null:1100 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server null:1100 [Root exception is java.net.UnknownHostException: null]]
        at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:269)
        at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1385)
        at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:594)
        at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:587)
        at javax.naming.InitialContext.lookup(InitialContext.java:351)

Is this behaviour is correct or not ?

And lookup code is like this

  | Properties p = new Properties();
  | p.put(Context.URL_PKG_PREFIXES, IConstants.URL_PKG_PREFIXES);
  | //Host is coming from jboss.bind.address property       
  | String host = System.getProperty(IConstants.SYSTEM_HOST_PROP);
  | // HA-JNDI url.
  | p.put(Context.PROVIDER_URL, host + ":" + IConstants.PROVIDER_URL_PORT); 
  | InitialContext ctx = new InitialContext(p);
  | //looking for jms queue destination
  | ctx.lookup(...)

Another problem is i tried to put localhost instead of host variable, however in that case it was ont wokring on both the nodes so i did change it to jboss bind address to ensure it picks from the node hwre code is getting executed.

Any help would be appreciated.
