How do I onfigure a simple socket server (TEXT)?

[hurzeler]

I need help!
How do I go about to create a simple text socket server that I can communicate with for example via telnet? I use JBoss4.0.5GA and JBoss4.2.0GA.

On JBoss4.0.5GA the problem I am facing is that the un/marshaller does not get used. On JBoss4.2.0GA I get

--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---

ObjectName: com.test:service=Connector,transport=socket

 State: FAILED

Reason: org.jboss.remoting.InvalidConfigurationException: The invoker for locator (InvokerLocator [socket://localhost:8084/?dataType=invocation&enableTcpNoDelay=true&marshaller=com.test.socket.V75SocketServer.TextMarshaller&socketTimeout=600000&unmarshaller=com.test.socket.V75SocketServer.TextUnMarshaller]) is already in use by another Connector. Either change the locator or add new handlers to existing Connector.

I can see that a socket server is defined in server/default/conf/jboss-service.xml but I would think it should be possible to stick another socket server on a different port.

<server>
 <!-- ==================================================================== -->
 <!-- Invokers to the JMX node -->

 <mbean code="org.jboss.remoting.transport.Connector"

</server>

Thanks for your help.
