Yes, I have read it. I have this line in jboss-app.xml:

> <loader-repository>org.test:loader=jboss-test.ear</loader-repository>

When I added just this part from the documentation to my deploy/ejb3-connectors-jboss-beans.xml:
>  <bean name="remoting:serverConfiguration"
>          class="org.jboss.remoting.ServerConfiguration">
>       <property name="invokerLocatorParameters">
>          <map keyClass="java.lang.String" valueClass="java.lang.String">
>             <entry>
>                <key>loaderport</key>
>                <value>5544</value>
>             </entry>
>          </map>
>       </property>
>       <property name="serverParameters">
>          <map keyClass="java.lang.String" valueClass="java.lang.Object">
>             <entry>
>                <key>remoteClassLoaders</key>
>                <value>
>                  <list elementClass="java.lang.ClassLoader">
>                    <value>jboss-test.ear:classloader</value>
>                  </list>
>                </value>
>             </entry>
>          </map>
>       </property>
>       ...
>    </bean>

nothing happened. The only lines in log were:

> 13:28:59,808 TRACE [org.jboss.remoting.serialization.impl.java.JavaSerializationManager] Creating ObjectOutputStream
> 13:28:59,809 TRACE [org.jboss.remoting.serialization.impl.java.JavaSerializationManager] Creating ObjectInputStreamWithClassLoader
> 13:28:59,809 TRACE [org.jboss.remoting.transport.socket.SocketServerInvoker] passed through ServerSocketRefresh.release()
> 13:28:59,825 TRACE [org.jboss.remoting.transport.socket.ClientSocketWrapper] reset timeout: 60000
> 13:28:59,884 TRACE [org.jboss.remoting.transport.socket.ServerSocketWrapper] ServerSocketWrapper[Socket[addr=/ip,port=40042,localport=3873].bc9678] wrote CLOSING
> 13:28:59,885 TRACE [org.jboss.remoting.transport.socket.SocketWrapper] ServerSocketWrapper[Socket[addr=/ip,port=40042,localport=3873].bc9678] closing socket

> 13:28:59,885 DEBUG [org.jboss.remoting.transport.socket.ServerThread] WorkerThread#20[10.0.4.75:40042] closed socketWrapper: ServerSocketWrapper[Socket[addr=/ip,port=40042,localport=3873].bc9678]

I also needed to add this (documentation has nothing about it):
> <bean name="org.jboss.ejb3.RemotingConnector"
>     class="org.jboss.remoting.transport.Connector">
> 
>     <property name="invokerLocator">
> 
>       <value-factory bean="ServiceBindingManager"
>         method="getStringBinding">
>         ...
>         <parameter>socket://${jboss.bind.address}:${port}?*loaderport=4873*</parameter>
>         ...
>       </value-factory>
> 
>     </property>
>     <property name="serverConfiguration">
>       <inject bean="ServerConfiguration" />
>     </property>
>   </bean>
Then log becames:
> 13:37:22,331 DEBUG [org.jboss.remoting.marshal.MarshallerLoaderHandler] MarshallerLoaderHandler received invocation with param of load_class and data type of null
> 13:37:22,331 DEBUG [org.jboss.remoting.marshal.MarshallerLoaderHandler] MarshallerLoaderHandler: loading class: *my interface*
> 13:37:22,331 TRACE [org.jboss.remoting.loading.ClassUtil] trying to load class: *my interface* from path: *my interface class file*
> 13:37:22,332 TRACE [org.jboss.remoting.loading.ClassByteClassLoader] getResourceAsStream =>*my interface* = null
> 13:37:22,332 DEBUG [org.jboss.remoting.marshal.MarshallerLoaderHandler] unable to load class *my interface*
> 13:37:22,332 DEBUG [org.jboss.remoting.marshal.MarshallerLoaderHandler] MarshallerLoaderHandler: returning class: *my interface*: ClassBytes [class=*my interface*,value=null]
Still confused why there is no any example of remote class loading in the documentation.
