Something else that I had working in a broadcast discovery environment that I can't seem to get working now in a static cluster environment is HA failover.

My hornetq-configuration.xml defines the cluster like so. The netty connector is the primary and netty-backup is the backup. (I've also tried it with just netty-backup.) When I bring them both up I see the backup announcement and when I kill the primary the backup takes over.

   <!-- Clustering configuration -->

   <cluster-connections>

      <cluster-connection name="my-cluster">

         <address>jms</address>

         <connector-ref>netty</connector-ref>

         <retry-interval>500</retry-interval>

         <use-duplicate-detection>true</use-duplicate-detection>

         <max-hops>1</max-hops>

         <static-connectors>

            <connector-ref>netty</connector-ref>

            <connector-ref>netty-backup</connector-ref>

         </static-connectors>

      </cluster-connection>

   </cluster-connections>

I've defined my connection factory in hornetq-jms.xml like so:

   <connection-factory name="NettyConnectionFactory">

      <connectors>

         <connector-ref connector-name="netty"/>

      </connectors>

      <entries>

         <entry name="/ConnectionFactory"/>

      </entries>

      <ha>true</ha>

      <confirmation-window-size>1</confirmation-window-size>

      <client-failure-check-period>100</client-failure-check-period>

      <retry-interval>1000</retry-interval>

      <retry-interval-multiplier>1.0</retry-interval-multiplier>

      <reconnect-attempts>10</reconnect-attempts>

   </connection-factory>

I've tried it both with and without confirmation-window-size (which the docs say are required but isn't set in the sample) but that doesn't seem to help. With reconenct-attempts set to 10 I'll eventually get

org.hornetq.core.logging.impl.JULLogDelegate warn WARNING: Tried 10 times to connect. Now giving up on reconnecting it.

But if I set it to -1 then my producer just hangs continuously attempting to reconnect to the dead server. Did I miss something in the config?
