Error writing to JMS queue

Question

I am trying to write to a JMS queue using the following cod:
Hashtable rmiEnvironment = new Hashtable();
rmiEnvironment.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.rmi.RMIInitialContextFactory");
rmiEnvironment.put(Context.SECURITY_PRINCIPAL, "admin"); // username
rmiEnvironment.put(Context.SECURITY_CREDENTIALS, "welcome"); // pwd
rmiEnvironment.put(Context.PROVIDER_URL,"ormi://10.10.50.50:9127/APP");
Context ctx = new InitialContext(rmiEnvironment);
QueueConnectionFactory queueConnectionFactory = (QueueConnectionFactory)ctx.lookup("jms/APP_QueueConnectionFactory");
The last line throws this exception:
javax.naming.NamingException: Lookup error: java.io.EOFException: Disconnected; nested exception is:
     java.io.EOFException: Disconnected [Root exception is java.io.EOFException: Disconnected]
     at com.evermind.server.rmi.RMIContext.lookup(RMIContext.java:176)

On the server side (OC4J standalone), in jms.log the following is printed:
javax.jms.JMSException: [PROTOCOL ERROR] JMSRequestHandler[5:testsrv:46202]: "JMS protocol" error, expected "-559,038,735", got "-485,684,723".

For the record, if you want to run that sample code:
http://www.oracle.com/technology/sample_code/tech/java/jms/index.html
edit the classpath section of build.xml (provided with sample) as follows:
<!--Set the classpath-->
<path id="classpath">
     <pathelement location="${OC4J_HOME}/j2ee/home/lib/jms.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/lib/jndi.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/oc4jclient.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/lib/javax77.jar"/>
     <pathelement location="${OC4J_HOME}/lib/dms.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/lib/bcel.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/oc4j-api.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/oc4j.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/lib/oc4j-internal.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/oc4jclient.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/rmic.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/lib/adminclient.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/lib/connector.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/lib/jmxri.jar"/>
     <pathelement location="${OC4J_HOME}/j2ee/home/lib/jta.jar"/>
     <pathelement location="${OC4J_HOME}/opmn/lib/optic.jar"/>
</path>
(class packaging has changed since this sample was written. Note that the above is really a superset of classes you would need for that simple example).
