My legacy application used JBossMQ successfully, however after migrating to JBoss6 (and HornetQ) i am getting the following exception:

10:37:44,361 ERROR [STDERR] javax.naming.NamingException: Could not dereference object [Root exception is javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalException: error unmarshalling return; nested exceptio

My hornetq-jms.xml file is pretty standard:

<configuration xmlns="urn:hornetq"

            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            xsi:schemaLocation="urn:hornetq /schema/hornetq-jms.xsd">

        <connection-factory name="NettyConnectionFactory">

           <connectors>

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

           </connectors>

           <entries>

                 <entry name="/ConnectionFactory"/>

                 <entry name="/XAConnectionFactory"/>

           </entries>

        </connection-factory>

<!-- JMS destination definitions for AIA updated for JBossAS using HornetQ -->

    <queue name="myQueuet">

        <entry name="/queue/myQueue"/>

    </queue>

</configuration>

Anyone have an idea what's going on?
