It works well in JBoss 5.

ejb3-connectors-jboss-beans.xml

<bean name="org.jboss.ejb3.RemotingConnector"
      class="org.jboss.remoting.transport.Connector">
  <property name="invokerLocator"> 

    <value-factory bean="ServiceBindingManager"
      method="getStringBinding">
      <parameter>
        jboss.remoting:type=Connector,name=DefaultEjb3Connector,handler=ejb3
      </parameter>
      <parameter>
        <null />
      </parameter>
      <parameter>socket://${jboss.bind.address}:${port}/?loaderport=4873</parameter>
      <parameter>
        <null />
      </parameter>
      <parameter>3873</parameter>
    </value-factory>

  </property>
  <property name="serverConfiguration">
    <inject bean="ServerConfiguration" />
  </property>
</bean>

But when trying to load class on the client I have the following exception:
