Ho fatto un classe in java che dovrebbe inviare un messaggio a jboss ma quando mando in esecuzione il mio applicativo ho la seguente risposta

xception in thread "main" javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: org.jboss.mq.referenceable.ObjectRefAddr (no security manager: RMI class loader disabled)]
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:722)
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:587)
at javax.naming.InitialContext.lookup(InitialContext.java:351)
at erasmo.jms.Sender.main(Sender.java:45)

Potere darmi un mano?
